Unfortunately, water can't make diamonds and glass significantly different from their refractive indexes.
So when Yun Wei poured the broken diamond and broken glass into the glass, there was still no obvious difference between the broken diamond and the broken glass, both of them emitted almost the same reflection, and there was no difference with the naked eye.
Fang Lisha couldn't help but say: "Yunwei, don't waste everyone's time, it's only one minute, don't think you can complete this assessment." ” Yun Wei smiled and sprinkled the thing she was holding in her hand into the clear water in the glass, and the clear water slowly changed, becoming a little cloudy and heavy.
But as she sprinkled the substance in her hand, a miracle occurred, some of them emitted a very bright light, the glow of which was hard to ignore, and some of them gradually disappeared from the light and color, and merged with the water.
Yun Wei breathed a sigh of relief and said, "Leng Shao, what is shining now is diamond, and what is consistent with the color of water is glass."
If you want to pick out the crushed diamonds and broken glass, you just need to shine a light and pick out the glowing ones. ” Ming Yeleng was a little shocked in his heart, Yun Wei finally solved the problem Her ingenuity, although she understands it in the cold night, but this time she really saw it.
He looked sideways at Yun Wei, who always had a smile on her face, but she didn't have much pride.
Fang Lisha saw that Ming Ye Leng kept looking at Yun Wei, and couldn't look at it, so she immediately said: "Leng Shao, don't believe Yun Wei, you said it, you can only use the things in this conference room to solve the problem, what she was holding in her hand just now is obviously that she brought it in from the outside, she cheated, Leng Shao, she must have used some chemicals brought in from the outside, what kind of heavy liquid separation and other methods" The other students also didn't believe that Yun Wei could solve the problem so easily, and looked at Yun Wei happily.
Yun Wei spread out her palms and said, "Indeed, I put some things in the clear water.
The refractive index of glass is completely different from that of diamond, and even the refractive index of glass, water and diamond is not the same, so when you put it together, it is the same as if you put it in air, there is no difference.
However, if the refractive index of water is made to be the same as that of glass, then the glass can be integrated with water, and diamond is particularly attractive because of its different refractive index from the other. ” "Your explanation can convince us, but you can't convince us with what you use," said one boy.
Several other candidates also shook their heads: "If the examination questions are not clear, it is not in line with the rules of the exam, Leng Shao."
Ming Ye looked at Yun Wei coldly: "Yun Wei, what do you say" Yun Wei said with a smile: "The thing I use in my hand that can make the refractive index of water become the same as glass is very simple, it is just salt.
This is what I found when I was pouring water over there, and I grabbed it in the palm of my hand.
It's not uncommon for this salt to appear in conference rooms, and I've heard that many people use salt to wash cups with tea stains.
When there is a meeting in the conference room, many teachers like to drink tea, and it seems to be normal for the school to prepare salt here."
Hearing Yun Wei say this, everyone realized that there was indeed a bag of salt in the place where the water was poured, and it seemed that it had been placed there a long time ago. aa2705221:
