Thanks to the apprentices' efforts, a simple experimental table was quickly built.
There are only three things on it.
On the left is a candle, in the center is a partition with a tiny hole, and on the right is a stone wall.
Sanchez lit the candle, and a candle-shaped light spot immediately appeared on the stone wall opposite, but it was upside down.
"We can imagine that the light emitted by the candle flame is composed of countless light spots. Since the diameter of the flame is larger than the hole, the light spots emitted from the upper part of the candle flame will pass through the small hole in a straight line and shine on the bottom of the wall, while the light emitted from the lower part of the candle flame will shine on the top of the stone wall. All the light spots combined together form an inverted candle flame!"
"If light is a wave, then it would not be possible to show such an inverted, clear image with completely opposite shapes and sizes!" Sanchez said loudly. "So there is no doubt that light is a particle that travels in a straight line!"
Sanchez's voice continued to echo in the exhibition hall, and the wizards present looked at the conspicuous candlelight on the stone wall and talked among themselves.
"Then how do you explain the interference and diffraction of light?" Jeffrey, who had been silent all this time, finally couldn't help but speak, and his first question revealed the deadlock of the particle school.
"This is exactly what I'm going to do next!" Sanchez said with a mocking smile. "All it takes is a simple simulation to make everything clear!"
Sanchez immediately ordered people to remove the candles and replace the middle baffle with a double-slit one. He then created another elemental group glowing blue in his left hand.
"Now I assume they are photoelectrons!"
Sanchez held up two elemental balls, one red and one blue, and shot them towards the two gaps in the baffle under the gaze of everyone!
After these two groups of particle elements hit the hole with a smaller diameter, the protective film on the outside burst directly, and the magical mimicry elements inside began to spread in all directions.
Since there were two explosion sources at the same time and the distance between them was very close, many scattered red and blue elements quickly collided with each other and fused together, making the power even stronger.
The wizard in the front row suddenly stood up from his seat, staring at the stone wall.
The red and green mimicry elements hit the wall, leaving behind eye-catching holes. About three seconds later, the result was out. The landing points of the scattered elements were concentrated in several areas, forming nine stripes formed by impact holes.
It's not that there are no holes in the middle of these stripes, but there are relatively few of them.
"Interference fringes, these are interference fringes!" Sean shouted in astonishment.
More and more people have realized that if these potholes are compared to scattered light particles, then the areas with dense potholes are the brightest areas, and the rest of the areas are relatively dark.
In other words, even if light is a particle beam, light interference and diffraction may occur!
Realizing this, the wizards who supported the light particle theory were all very excited. Sanchez's experiment undoubtedly eliminated the biggest obstacle to the particle theory. For a while, cheers and applause echoed in the exhibition hall.
The great wizard Arad directly read out the result and shouted loudly, "This is the victory of particle theory!"
Sanchez turned his gaze towards Jeffrey and Anthony with a smug look.
"I have to say, this explanation is very clever, Sanchez!" Anthony couldn't help but exclaim.
He had read the theory of photoelectron explosion proposed by Sanchez, but he did not expect that the other party had actually carried out this experiment, although it was only the result of an experimental simulation of photons.
"I'm sorry you gave up on the right path, Anthony." Sanchez said with a chuckle. "It's not too late to repent now!"
Anthony shook his head and sighed, "Unfortunately, this theory is wrong!"
Seeing that Anthony was still stubborn, Sanchez frowned in dissatisfaction, but before he could reply, Anthony spoke again and said in a decisive tone.
"Because I have found the essence of light. It is actually... an electromagnetic wave!"
Chapter 508: Before entering the quantum realm, please throw away the common sense in your mind!
Anthony's words made the particle school wizards who were celebrating their victory happily pause.
"Master Anthony, are you sure?" A wizard who supported the wave theory stood up excitedly, then hesitated. "But, how is this possible?"
Apparently, even he himself was not sure about this statement.
What is electromagnetic wave? It is a wave phenomenon caused by the alternating changes of electric field and magnetic field.
The entire kingdom's communication system relies on the use of electromagnetic waves, so wizards who are proficient in electricity are no strangers to it.
That's why they found it unbelievable. If, as Anthony said, light was an electromagnetic wave, then when they communicated, there should have been an extremely obvious light wave!
"To be precise, light is an electromagnetic wave in a specific frequency band." Anthony raised his voice a little, suppressed the chaotic doubts on the court, and then explained. "And electromagnetic waves of other frequencies cannot be received by our eyes, so we can't see them!"
"You mean that light waves are like sound waves?" Harof's mind moved, and he quickly understood the underlying meaning of Anthony's words.
Because there is something similar that they are very familiar with, and that is the sound waves generated by the vibration of objects!
Due to the limitations of the human ear, we can only hear sound waves with a frequency of about 20 to 20,000 Hz. Once the frequency exceeds or is lower than this, we cannot hear it.
As for Hertz, it refers to the measurement of the number of repetitions of periodic changes per second. It is described in detail in Lynn's book "The Secret of Sound - The Principle of Resonance". It is said to be named after a deceased scholar in the "Society of Secrets" who studied sound waves.
"That's right!" Anthony nodded. "According to my experiments, the frequency of visible light is about 400 to 700 Hz."
"That is to say, we can create light by releasing electromagnetic waves!"
"Just like this!" Anthony raised his hand, the electric field and magnetic field alternated, and a dazzling beam of light shot out from his fingertips.
"Light, it's really light!" A group of wizards from the particle school looked at this scene in horror, their faces turned pale, because this meant that Anthony was not lying, and light was indeed an electromagnetic wave.
Sanchez and Arad's faces were also filled with disbelief.
Lynn was very interested in Anthony's technique of using electromagnetic fields to quickly alternately emit light beams. This meant that many steps could be saved when using laser magic in the future, thereby greatly improving the speed of launching light magic.
This is also the necessity of developing magic science. One only needs to point out a direction, and there will always be powerful people who can innovate it. Otherwise, if he alone wants to magicalize many scientific research theories and tap their potential, he will be exhausted.
"I think the speakers can come to a conclusion now, right?" Jeffrey said with a smile.
Anthony's research is undoubtedly the most direct evidence of the light wave theory. Even Sanchez cannot change the fact that light is an electromagnetic wave!
The only thing that made Jeffrey feel a little regretful was that there was only one Corona Medal but it had to be shared between the two of them. It might be disassembled into several Silver Moon Medals. This way, he would miss out on the highest honor in the wizarding world!
"Wait... Speakers, I have another question!" Just as Jeffrey was thinking, Arad suddenly stood up and interrupted. "If light is a wave, how do we explain its particle properties?"
Jeffrey replied impatiently. "These are just some side issues. The facts are right in front of us. You can't deny that light is an electromagnetic wave, right? As for the mystery of light waves, it is definitely not something that can be thoroughly explored in a few months. As long as we follow the right path of thought and continue to study, one day these problems will not be a problem anymore!"
Harof, who was sitting in the judges' seat, also nodded. Now they should first figure out the nature of light and resolve the [casting obstacles] of lightning wizards. It would not be too late to study it slowly later.
However, Arad insisted, "So what if light is an electromagnetic wave? How can you prove that electromagnetic waves are not made up of particles?"
"You know, any wave needs a medium to propagate, but electromagnetic waves don't. I've long suspected that it's not a real wave, but a particle!"
Arad's imagination completely confused Anthony.
Are electromagnetic waves particles?
Are you kidding? This thing is actually transmitted in the form of waves!
However, this explanation also allowed the wizards who believed in light particles to regroup. After all, particle theory can explain the phenomena of light interference and diffraction, but Sanchez and Anthony could not explain the principle of pinhole imaging using light wave theory.
So maybe this electromagnetic wave...it is also a particle!
The large exhibition hall that accommodated tens of thousands of people soon became noisy, with arguments and discussions continuing.
Harof, Aurora and Vittorio all had frowns on their brows at the judges' table. When Anthony proposed that light was an electromagnetic wave, they all thought that the dispute had come to an end. However, Arad suddenly spoke, causing them to hesitate again.
"If there is no other more powerful evidence to prove that light is a particle, then I think the wave theory of Master Jeffrey and Master Anthony is more in line with the nature of light." Harof said after pondering. As a master of force field magic, he naturally prefers the wave theory.
After all, there are many similarities between the two. Maybe just like when they cast force field magic, space is the medium for electromagnetic waves.
Vittorio nodded, and agreed that the wave theory was more feasible.
Aurora on the side objected. "We can't jump to conclusions so easily. Many properties of light are still under discussion."
Obviously, she supported the light particle theory.
After several speakers expressed their opinions, everyone present turned their eyes to Lin En.
As the originator of the law of free fall, universal gravitation and element orbit model, the authority of this magic star in magic research is unquestionable!
Under the gaze of tens of thousands of eyes, Lin En looked at Anthony and spoke slowly. "Your research is very correct. Light is a kind of electromagnetic wave!"
As soon as these words were spoken, all the wizards who believed in light waves showed smug smiles on their faces. It seemed that Speaker Lin En was more supportive of their light wave theory.
Sanchez, Arad and others looked very ugly. With the three speakers, Harof, Vittorio and Lynn, endorsing the light wave theory, it is likely that the light particle theory will be thrown into the trash after this seminar.
"This is exactly derived based on your Maxwell equations!" A slight smile appeared on Anthony's face.
Jeffrey was not surprised at all, because he had already read Lynn's reply to Anthony and was very clear about the attitude of this magic star.
What surprised the two was that after Lin En finished speaking, he suddenly turned to Sanchez again and spoke with appreciation.
"Your argument is also very good. Just like, light does have some properties of particles, and the speculation that electromagnetic waves are particles is also very bold..."
After hearing this, Sanchez, who was sighing, suddenly raised his head and looked at the magic star in disbelief.
The smile on Anthony's face froze, and he was a little confused as to why Speaker Lynn suddenly agreed with Sanchez's point of view.
Could it be that the other party feels that the light wave theory still has some loopholes, so he plans to delay for a while before drawing a conclusion?
Harov also thought of this, and raised his voice a little, reminding him, "Chairman Lin, now that [Spellcasting Obstacles] are spreading throughout the kingdom, it would be best if we could come to a conclusion on the nature of light at this seminar!"
"No, I think you misunderstood me, Speaker Harrov." Lynn shook his head, looked at the wizards in the exhibition hall, and said with a smile.
"I mean, is it possible that light is both a particle and a wave?"
Lin En's voice was not loud, but it was transmitted very accurately to the ears of everyone present. However, everyone who heard it couldn't help but wonder if they had heard it wrong.
Is light both a particle and a wave?
"Please forgive my intrusion, but could you explain what this means?" Jeffrey frowned and said in great confusion.
"Is it like a rope, which looks continuous on the surface but is actually made up of individual elements?" Arad said with a creative mind.
Sanchez nodded. This sounded very reasonable and his photoelectron burst theory perfectly corresponded to what the Magic Star had just said.
Most importantly, this means that particle theory is the real core, and waves are made up of a large number of scattered particles.
However, Linn calmly rejected Arad's idea. "What I mean is that light has both particle and wave properties, just like what we saw in the experiment just now."
"It's both a particle and a wave? This is impossible and goes against common sense!" Jeffrey couldn't help but say.
Some wizards from the empire were extremely disappointed with this famous magic star. When it was Lin En's turn to speak, they were all expecting the other party to come up with some amazing argument to end the wave-particle dispute that had lasted for several months.
The results now seem shocking indeed, but the argument is totally illogical and can only be described as bizarre!
Waves are waves, particles are particles, and their forms of existence are completely different.
For example, they release a high-frequency shock wave that can cut a wall in half, while a high-speed impacting particle can only make a large hole in the wall.
For example, a wave can pass through several slits at the same time and even split into more microwaves, but can a particle do that?
Of course it’s impossible!
Lin En was not angry at the doubts of the crowd. He raised his voice slightly to suppress the discussion of the crowd. "Master Jeffrey, what do you think common sense is?"
