Scholar’s Starry Sea

After reviewing his identity, Wu Bin soon went to the exam laboratory under the guidance of the teacher.

'It deserves to be a university laboratory...' Looking at the huge and bright Physics laboratory, Wu Bin couldn't help feeling deeply.

Next, the invigilator teacher announced the rules of the test room and various precautions. At 10 o'clock, the test started on time.

There is only one experimental question. What is required is to study the Physics characteristics of optical glass materials (wavelength range is 400~700nm)

Next, Wu Bin read all the experimental equipment, materials and After three questions, I couldn't help but sweat.

"Wow, it's real..."

There are two main tools used in this experiment. One is a common spectrometer, which is used to measure angles, and then get Some Physics parameters, such as grating constant, refractive index, etc.

The other monochromator is not often used, but the basic Physics principle is also mentioned in the competition textbook, so Wu Bin is not unfamiliar.

But this experiment combines these two experimental instruments!

This is new! At least Wu Bin has never played...

'It's worthy of being an experimental question in the finals, it's a show...'

But it's a show, but it's finally not disgusting to Wu Bin. The point of starting, just need to use more brains.

So Wu Bin adjusted the spectrometer first, and then inserted the sleeve at the exit slit of the grating monochromator into the collimating tube of the spectrometer, and turned on the power to light up the LED......

p>

While doing it, Wu Bin suddenly found that the person who wrote the question was quite conscientious. In fact, he reminded many details in the question.

For example, don't ask whether the Physics performance of the main homemade small grating monochromator is very stable, whether the spectrometer has adjusted the relevant parts and then re-adjusted it in a large range, etc.

The difficulty of the first question is not too high, as long as you can skillfully use the experimental equipment, you can complete it.

But the second question is the experimental principle of measuring the dispersion curve of glass materials is quite cumbersome.

"Tsk..." Wu Bin closed his eyes and meditated for a while.

'The dispersion phenomenon of an optical material refers to the macroscopic performance of the material's refractive index n or absorption coefficient α with the light wave wavelength λ...'

'Hmm! There is an idea! '

Wu Bin snapped his fingers, and then began to measure the minimum deflection angle of the monochromatic light wave corresponding to the Mitsubishi mirror with a spectrometer.

As long as there are ideas, the experiment questions are easier to follow. Although the process is a bit difficult, Wu Bin finally completed the third question after spending two hours.

……

When the exam was over and returned to the hotel, Wu Bin saw the scene as expected, and the hall was "wandering" all over the hall with gloomy candidates.

Because he still thinks he is very strong in the experimental questions, and this question that he even thinks of Sao, even the group of Heaven's Chosen Child who can make it into the national competition, it is estimated that they will have to be disgusting. no.

The Shanghai team said that the meeting point was on the second floor. When Wu Bin walked up, he found that almost everyone else was already there. At the moment, he was holding a group and scolding his mother.

"Say a good experiment question is to send warmth??"

"Stop talking, this question is really showing my scalp numbness, I just look for it It took an hour and a half for the plane mirror to reflect back to the crosshairs in the telescope! There was no time to do it later."

"I also adjusted the dimming axis perpendicular to the axis of the instrument for a long time, wow...it’s a real adjustment. It’s very popular."

……

Such complaints are generally seldom heard, because the unwritten rule is not to discuss the content of the test after the test. .

But it is estimated that the experimental questions this time are really insatiable, and that's why everyone was crazy about it.

"Oh, God Wu is here, are the experimental questions exciting?" Lu Xuange shouted as soon as he saw Wu Bin.

"Excitement, indeed excitement." Wu Bin nodded.

"Yeah~ I'll tell you..."

So almost everyone was complaining about this experimental question until dinner time, although Wu Bin thought they complained In fact, some of the details are reminded in the title, but they did not pay attention, but it is better not to mention it at this time.

After all, many times I see through but don’t understand, I’m still a good friend.

But no matter how hard the process is and the results are unacceptable, the National Physics Competition for high school students at this time has finally come to an end. All that is left is to wait for the announcement of the scores and rankings.

Wu Bin did not eat dinner with everyone. His two teachers came from thousands of miles away, and he naturally wanted to accompany them.

It was quite interesting to chat with the two teachers about the theoretical examination and experimental questions during the meal.

……

Before the announcement on 2nd day in the morning, the competition committee organized the students to visit the Hongyan Link, among which is included Hongyan Village, White Mansion, and the scum Hole, enhance the party spirit of a wave of students.

It's just that the teacher can obviously feel that the students have no interest in visiting, so I returned to the hotel after the visit early.

After eating a buffet, at 4 pm, the score... finally announced.

"Mom...I don't dare to check it."

The Shanghai team got together early, and Zhao Kehan, standing next to Wu Bin, was full of sweat.

"There is nothing to dare to do. It is a knife to stretch your head and a knife to shrink your head. It's better to hurry up." Lu Xuange said and went to check the score.

"Fuck!!!"

Just when everyone was entangled, Lu Xuange suddenly broke out a foul language.

"What's wrong, you joined the National Team? So excited." Xiao Songyang glanced at Lu Xuange and asked.

"I can't get into the National Team. I haven't seen it yet... but God Wu has entered. He is very first! Fuck, I don't know what to say except Fuck!"

Lu Xuange's words made everyone stunned. Even Wei Tianshuo stood up in shock, and quickly looked at the newly announced Ranking List with his classmates.

Province: Huhai, School Name: Xiaguang Middle School, Student Name: Wu Bin, Gender: Male, Grade: Senior Three, Theory: 270, Experiment: 79 Total Score: 349 Ranking: 1

Province: Hubei, School Name: No. 1 High School of China Normal University, Student Name: Gong Chengwei, Gender: Male, Grade: Sophomore, Theory: 265, Experiment: 75 Total Score: 340 Ranking: 2

Province: Hu Nan, School Name: Yali Middle School, Student Name: Zhang Fu, Gender: Male, Grade: Senior Three, Theory: 255, Experiment: 70 Total Score: 325 Ranking: 3

……

"My day...God Wu amazing!" Zhao Kehan ​​shouted fiercely and patted Wu Bin after watching.

"I'm a strong horse! It's almost a ride with the second monster, and scored more than twelve points in the third place! What's so...My knees are a bit soft."

p>

"Tell me, I really didn't expect. Although I know God Wu is great, I really didn't expect...God Wu! God Wu! Let me hug your legs!"

……

After checking the scores, the rest area on the second floor is simply chaotic, and Wu Bin, as the person involved, is actually in a very delicate mood at this moment.

'My theory question was deducted 10 points? ? ? '

You must know that he is confident that he can get full marks after he finishes it, and now it's an uncomfortable batch!
