The world of counterfeit magistrates competes in the world

Chapter 590

After this incident, it is conceivable that Lin Yifan was blocked from the door by Luo Qing'er that night.When he wanted to go to Yunyang to rest, Yunyang also cared about Qing'er's feelings and refused to let Lin Yifan in.In desperation, he had no choice but to order Niu Dali to build a small bed in the study, and slept here for the past few days.

In order to make up for the rift in the relationship between father and son caused by this incident.Lin Yifan made a more exquisite Kongming lantern by himself and gave it to Lin Gan.

With the Kongming lantern, Lin Gan finally showed a smile, and soon forgot the harm his father had caused him.

But Lin Yifan ordered people to investigate the details of that gentleman, and only then did he know that the Mr. Li mentioned by Lin Gan was named Li Nanguang, and he was a teacher who specialized in teaching miscellaneous subjects to schoolchildren.The so-called miscellaneous learning refers to knowledge other than bibliography.This is a subject specially established by Lin Yifan in Hengshan, with the intention of allowing students to learn a lot and broaden their horizons.

And this Mr. Li is originally a scholar in Huazhou. He likes to collect local customs and customs, as well as the so-called strange skills. Coupled with his withdrawn personality, he often hides in the room alone and tinkers with some incomprehensible things. .Therefore, he doesn't fit in well with the scholar circle in Huazhou.

Later, when Guo Huaili was preparing for the Huayuan Academy, Li Nanguang came to the academy to apply for employment due to his livelihood.In the end, he was successfully recruited as Mr. Mengtong Miscellaneous Studies.

After reading the investigation report, Lin Yifan became more interested in this Li Nanguang.You know, scholars in today's world are good at everything, but their hands-on ability is particularly poor. They take everything for granted and make up their own brains. Of course, the result is ridiculous.But this gentleman is different. He is interested in the so-called heresies outside the sages' articles, so this person is interesting.

On this day, with nothing to do, Lin Yifan dressed in scholar's attire and went straight to visit Huayuan Academy.

When he walked to Mengtong School, he heard the cheers from the children inside, and walked over curiously.

On the podium of this classroom, a tall and thin young man is demonstrating a prism refraction experiment.He placed the Prism in his hand under the slanting sun, adjusted the angle slightly, and a rainbow was reflected on the wall.It was because of this rainbow that the schoolchildren screamed with excitement.

Immediately afterwards, the gentleman saw that the children present were about to move, so he said with a smile: "Do you all want to play?"

"Think!" the schoolchildren immediately shouted without hesitation.

"Okay, start from the first row, come up one by one to see if you can hang the rainbow on the wall." The gentleman immediately waved his hand and recruited a schoolboy.

Next, after all the children had played with it, the gentleman said seriously: "Children, do you know how this rainbow came about?"

"I don't know!" The children also shouted without hesitation.

The gentleman seems to have gotten used to it, and immediately smiled and said: "It's very simple. According to my observation, in fact, the light of the other seven colors is mixed in the sunlight, and it is only because it is covered by the strong white light that we can't see it." Yes. Think about it, when the morning sun rises, when the white light is not very strong, its surroundings will turn red, but when the scorching sun is in the sky, the closer to it, the bluer the blue, almost There is only white light left, and the farther the distance, the deeper the blue, and gradually turn into a blue color. When the scorching sun turns into the setting sun, the color will turn into orange-yellow again, and after it sets, there will be only a touch of purple-black. Therefore, through this triangular lens, we can strip the seven colors in the sunlight and reflect them on the wall.”

(PS: The above is all my nonsense, please don't take it seriously.)
"But sir, why does this triangle reflect a rainbow?" At this time, the already-student couldn't help asking.

Li Nanguang's face froze slightly, and he couldn't help but smiled wryly: "Well, sir, I haven't understood the mystery of it yet, so I can't tell you yet."

"Papa papa!" At this moment, a burst of applause came from outside the classroom.Lin Yifan clapped his hands, walked into the classroom, and said with a smile: "What this gentleman just said is really refreshing."

Li Nanguang blushed slightly, and hurriedly cupped his hands and said, "This brother has won the prize."

After finishing speaking, the two looked at each other speechlessly, and fell into an awkward situation for a while.

Lin Yifan coughed dryly and said with a smile, "I just heard what Mr. said, and it seems that I still don't know why the mirror reflects the rainbow?"

"I'm ashamed, I don't know much about it, and I don't know anything about it." Li Nanguang's face became even more embarrassed.

"Haha, sir, knowing that light contains seven colors is already very remarkable." Lin Yifan laughed, "As for why this lens can reflect rainbows, I have some insights."

"Oh?" Li Nanguang looked at him in surprise, a hint of excitement flashed in his eyes, and quickly bowed deeply, "Please teach me, brother."

"I don't dare to teach you." Lin Yifan quickly helped him up, and said with a wry smile: "I also have only a half-knowledge about this, I can only understand it but not express it in words."

"Huh?" Li Nanguang looked at him suspiciously.

Lin Yifan ignored his doubts, and immediately stepped forward, poured a pot of water from the podium into a bowl, then poured a writing brush into the bowl, and showed it to Li Nanguang.

When Li Nanguang saw it, his eyes narrowed slightly. He saw that the brush was bent in the water.In fact, this kind of scene is occasionally found in ordinary life, but I didn't care about it at the time.Now that the other party is showing this to him, it is natural that they have ulterior motives.While the mind was spinning, there was a faint realization in my heart.

At this moment, Lin Yifan took the brush away, picked up the bowl of water and drank it.

"The water is dirty, bro..." Li Nanguang was about to stop it.Seeing Lin Yifan with water in his mouth, he came to the sun, with his back against the sun, and forcefully sprayed the water out.

The sprayed water was filled with sunlight, and for a brief moment, a rainbow appeared in the water vapor and passed by, but Li Nanguang really saw it.

"This, this is?" Li Nanguang ran under the sun in surprise, but at this moment he couldn't see anything.He immediately rushed to the podium, took the pot of water, took a sip, then stood where Lin Yifan had just stood, and sprayed vigorously.Sure enough, when the water vapor filled the air, the rainbow appeared again.

Li Nanguang was overjoyed, and sprayed it several times in a row, and he could still see a rainbow.At this time, Li Nanguang seemed to be in a daze, and suddenly burst out laughing, "I understand, light bends when it encounters water, and the triangle, like water, is transparent and tortuous, so when light enters the lens, it also bends." It bends. The bent light filters out the white light and reflects the colors of the rainbow."

In fact, Lin Yifan didn't understand the rationale. Seeing that Li Nanguang said it clearly and logically, he really thought that was the case.So, they applauded from the sidelines.

As soon as the teaching time came, Li Nanguang couldn't wait to invite Lin Yifan to his residence to chat about the novel ideas in his mind, as if he regarded Lin Yifan as a confidant.
