Chapter 82 New Inference [Please collect]
Lan Miaoren is a person who pursues perfection and perfection, and a person who pursues the truth incomparably. The truth that already exists cannot be desecrated or changed.
Therefore, when Zhuo Bufan said, "Light is not just a particle, but also a wave," Lan Miaoren seemed very excited.
The two looked at each other for probably nearly a minute. Lan Miaoren puffed up his proud chest, looked at Zhuo Bufan very confidently, and then said.
"It's very interesting. Are you saying that light, like sound, is a kind of wave?"
"Don't you think it's ridiculous? When I talk to you, you are not the only one who can hear me. That's because sound is a wave that can spread in all directions."
"But, if I use the Xuanguang Mirror to shine on you, the person who will be illuminated can only be you." The woman said, and actually picked up the Xuanguang Mirror and shined it directly at Zhuo Bufan.
"Do you know why this is? Because light is a straight line, and light always shines in a straight line. How can this be a wave?"
Facing Lan Miaoren's vicious questioning, Zhuo Bufan seemed a little overwhelmed.
The other students around him all remained silent and did not dare to speak out.
In their eyes, Lan Miaoren is a terrifying female devil.
"Can you put the Xuanguang Mirror away first, sir?"
Zhuo Bufan stretched out his palm to cover his eyes, and through the gaps between his fingers, he could see several thin stripes of alternating light and dark between the fingers. Isn't this the diffraction of light?
"Sir, I have a few questions about light. Can you answer them for me?" Zhuo Bufan straightened his clothes and sat up again.
"Okay, then you ask!" Lan Miaoren is not unreasonable. At least she has her own stubbornness in pursuing the truth, but at the same time she also respects other people's thoughts.
However, at present, she just regards Zhuo Bufan as a problem child and a student who has gone into misunderstandings in his studies.
"There is a proverb in the folk saying that looking at people through the crack in the door makes them look down upon. I was thinking about how it is possible to look down on people when looking at people through the crack in the door. Doesn't light propagate in a straight line? Later I did some research and found that the door If the seam is really small enough, it will really feel blurry when I look at that person. I don’t know how to explain this problem?”
"Also, the curtains in my house are made of linen with many small holes. When the sun is too bright, I will close the curtains. But when I close the curtains, the scenery outside the curtains can still be clearly seen. . Since the light is direct, the scenery I see should be a partial view of each hole. Why is there a panoramic situation? "
"Also, once I was playing with the Xuanguang Mirror at home. I set up a piece of black cardboard, and then opened a vertical slit in the black cardboard. When I shined the Xuanguang Mirror on the black cardboard, the light Projected through the gap on the wall, the same gap of light is indeed formed. This discovery makes me believe that light does travel in a straight line. "
"But I suddenly had a whim and set up another baffle behind the gap. This time there were two slits side by side on the baffle. Then I passed the light of the Xuanguang Mirror through the black cardboard. What do you think the result will be this time? "
Zhuo Bufan kept it secret and did not give the answer.
"You must have gotten two vertical rays, right?"
Some students answered without hesitation.
"Yeah, needless to say, you'll know it just thinking about it." The students were convinced of their guesses, thinking that they would know the result of this kind of thing just thinking about it, and it should be that result.
However, Lan Miaoren frowned slightly and looked at Zhuo Bufan with squinted eyes.
"Haha, just think about it. Everyone, many times, what you think is the absolute truth may be wrong when you do the experiment."
"In fact, when the light passes through the two gaps, it forms far more than just two light paths, but many."
The third problem mentioned by Zhuo Bufan is actually the famous double-slit interference. It was this famous experiment that proved the wave theory of light.
The particle theory that had existed unswervingly for hundreds of years was also broken because of this experiment.
Since there is no wave theory of light in this world, Zhuo Bufan transforms into "Fresnel, the light wave promoter" and breaks the only truth recognized by this world.
As soon as this statement came out, it immediately caused an uproar.
"Impossible, how can there be multiple light paths? This is impossible when you think about it."
"That's right, you can figure out the answer to this kind of question just by thinking about it."
Many people are still stuck in imaginary issues.
Indeed, if you just think about it in your head, light passing through a slit is a light path. So if light passes through two slits, it should also be two light paths. This is the human subconscious mind, which has already imprinted the truth that light propagates in a straight line deep into the mind.
It is wrong to use this idea to infer the results.
Zhuo Bufan didn't have time to argue with them in a paradoxical speech. You must know that the debate between waves and particles of light has been debated in the Western physics community for hundreds of years.
But facts speak louder than words. The predecessors brought the experimental results to the table, and all the talks on paper and all the arguments turned into a dream.
Practice is the only criterion for testing truth.
The ideas of philosophers still hold true in the face of science.
These people have never practiced it, so how do they know what the outcome will be?
Only Lan Miaoren looked at Zhuo Bufan blankly. She is the magician, the promoter of truth, the ascetic who seeks the truth.
She would not jump to conclusions, nor would she believe Zhuo Bufan's nonsense.
So, when she heard Zhuo Bufan's three questions in a row, she was indeed shocked.
However, this shock can only be hidden in her heart and cannot be expressed.
She is a teacher, a pioneer who leads these apprentices to the road of truth. She cannot be confused, nor can she create confusion.
So, the topic of "What is light" ends here in this class.
"Okay, time is limited, we will discuss this issue later. In the remaining time, I should teach you how to comprehend the dazzling spell from a beam of light through your own "listening" and "observation"!"
Lan Miaoren turned and walked onto the podium. Zhuo Bufan saw her expressionless face and couldn't help but smile slightly.
He knew that Lan Miaoren would do experiments after she went down, and when she saw the results of the experiment, she would be shocked beyond words.
Faintly, Zhuo Bufan felt that his arrival might change the world.
Da!
Lan Miaoren, who walked onto the podium, suddenly snapped his fingers. Then, all the windows of the classroom where Zhuo Bufan and his friends were were immediately closed.
In an instant, it was pitch black, the day turned into night, and you couldn't see your fingers.
Suddenly, a faint light appeared on the desk!
It was like a firefly, dancing gently in the air...
...
Someone in the book review area guessed what I was going to write later. The author felt very depressed and changed the outline. In addition, regarding the spell, I really want to use scientific methods to explain it. However, the author is just a primary school student who graduated from kindergarten, and the knowledge reserve is not enough. If there are many bugs, please don't pick on my mistakes. I will try my best to make sense and bring you a brand new reading experience. That's all!
