Amidst everyone's doubts, Lin En did not rush to explain, but asked rhetorically.
"You should all know that light can be reflected, right?"
The wizards in the auditorium all nodded. Reflection is the basic property of light, and most polarizing magic also uses this principle.
"The colors we see are actually caused by light shining on an object, then being reflected into our eyes, and recognized by photoreceptor cells." Lynn explained. "Human sensory cells can only distinguish three colors: red, green and blue. Since the visible solar spectrum is evenly mixed, it is colorless in our eyes..."
"Wait a minute, Master Lin En, if you say so, wouldn't everything be exactly the same color under the same kind of light?" Sanchez couldn't help but interrupt.
"Of course not, because part of the light is absorbed by the object, and what we see is only the reflected part of the visible light..." Linn said.
To put it more accurately, after the light reflected by the object enters the human eye, it is converted into electrical signals on the retina and transmitted to the brain through the optic nerve. The so-called color is just the human definition of the visual effect of electromagnetic waves in a certain frequency band of visible light. That’s all…
Regarding this point, after he mastered the electromagnetic force, he verified it in Iyeta, so he naturally has full confidence.
Lin En's words resounded throughout the auditorium, and the arguments and discussions in the audience became louder and louder.
"This theory is really... amazing!" Raphael looked at Linn and couldn't help but say. "Doesn't that mean that this world actually has no color?"
In the past, they believed that the elements themselves had a certain color, and the objects they combined would show the corresponding color system. Light only allowed them to see the colors that originally existed or were attached to the surface of the elements.
However, Lin En's statement is completely opposite. All colors come from light, and what they see is the light that is rejected by the object, but those that are absorbed cannot be seen?
In other words, a red object is not actually red at all. Instead, it reflects all red light and absorbs light of other colors.
Theoretically, if you can find a way to 'see' the 'light elements' inside an object, this thing should show a mixture of other colors?
Raphael had a hard time understanding Linn's words. It was really difficult to imagine a world with inverted colors.
"Yes, without light, there is no color." Linn nodded, acknowledging Raphael's words.
"This is simply a fallacy!" The great wizard in purple slapped the table and stood up, yelling loudly. "So everything we see is reversed. A black object absorbs all light and is actually very bright, but we can't see it?"
"No, we can't say that. Since the light has been absorbed and not reflected, it will naturally not light up." Linn shrugged and continued to speak.
"And you can think about it, if you stay in a sealed space at night, can you see colors? So colors rely on light to exist."
Hearing this, Rafael and others were stunned for a moment, and Sanchez frowned, feeling that Linn's statement was very unreliable.
"Master Lin En, magic requires rigorous demonstration, not guesswork! We can't see anything without light. Should we say they don't exist if we can't see them?" Standing on the high platform Glenn plucked up the courage to retort. He was the last person to believe this argument.
After all, this is related to whether he can obtain the Morning Star Medal. Once it is proven that the original color is not the essence of light, but a phenomenon caused by physiological reasons, the importance of his research results will plummet.
However, arguing with a great wizard is still the most popular magic star in the wizarding land. After the courage in Glenn's heart gradually faded, cold sweat began to break out on his forehead.
The friend next to him also quietly pulled his sleeve, signaling Glenn not to rashly contradict the magic star. The other party didn't even need to do anything. If he showed his intentions even slightly, their lives would be difficult in the future.
Linn didn't pay attention to Glenn's slightly sharp questioning and said with a smile. "A good rebuttal. What you said is also true. Every magic theory needs to be verified by experiments!"
"Now, please seal the windows and doors of this auditorium... Don't let any light in!"
After Lin En finished speaking, the wizards by the windows in the auditorium all cast spells to block all the doors and windows. The originally bright academic seminar site immediately became extremely dark, leaving only the tops of their heads. The light coming directly from the top of the tower provides a slight glow.
"Who wears a mirror?" Lin asked again.
"I have it on me!" Glenn took a step forward and took out a round mirror from his arms. He had been doing experiments on light recently, so of course the mirror would never leave his body.
"Very good!" Linn nodded, and then called Joni over, asking her to stand directly in front of the high platform, and used a round mirror to reflect the light falling from the top of her head onto the girl's body.
In the darkness, Jonny's figure was extremely conspicuous, wearing a bright red dress, the hem of which swayed gently, like a flame.
"Do you know what color clothes she is wearing?" Lin En asked.
"Of course it's red!" Glenn replied.
"Can't everyone see this?" Raphael curled his lips and didn't understand why Linn asked such a stupid question.
"Please remember your current judgment! The clothes are red, don't forget it!" Lin En said with profound meaning.
Raphael was speechless. Could this clothes turn blue later?
He wanted to see what the other party wanted to do!
Lin En turned his attention to the girl in the red dress and said with a smile. "Your skin is very fair and beautiful..."
Jonny also didn't expect that the dean would say this in public, and looked a little shy and uneasy in the ambiguous eyes of the wizards around him.
This is very suitable for experiments... Lin En swallowed the second half of the sentence silently.
"We need to use your... light dissociation device next!" Linn stepped forward and patted Glenn on the shoulder, greeting him.
"What should I do, Master Linn?" Glenn asked nervously, holding the invention in his hand.
"First decompose the light as we did just now..." Linn explained the steps to Glenn step by step in great detail. Only after confirming that the other party understood, did he announce that the experiment could begin!
