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

'It is worthy of the university's laboratory ......'Looking at the huge and bright physics laboratory, Wu Bin couldn't help but sigh in his heart.

Then the invigilator announces the rules and precautions of the exam room, and at 10 o'clock, the exam starts on time.

There is only one experimental question, which requires the study of the physical properties of optical glass materials (wavelength range of 400~700nm)

Then Wu Bin couldn't help but sweat profusely after reading all the experimental equipment, materials and three questions.

"Wow, that's really a sassy ......"

There are two main tools used in this experiment, one is the common spectrometer, which is used to measure the angle, and then obtain some physical parameters, such as grating constant, refractive index, etc.

The other monochromator is not used very often, but the basic physical principles are also mentioned in the competition textbook, so Wu Bin is no stranger.

But this experiment is a combination of these two experimental instruments!

That's fresh! At least Wu Bin hasn't played it......

'It's worthy of the experimental question of the finals, and it's really ......'

It's just a commotion, but it's not so disgusting that Wu Bin doesn't know where to start, he just has to use his brains more.

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

As he was doing, Wu Bin suddenly found that the questioner was quite conscientious, and he actually reminded a lot of details in the test questions.

For example, don't mainly make a small grating monochromator, whether the physical properties are very stable, whether the spectrometer has adjusted the relevant parts and then readjust it in a large range, etc.

The first question is not too difficult, as long as you are proficient in the use of experimental equipment, you can complete it.

However, the second question: 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 refractive index n or absorption coefficient of the material α with the wavelength λ of the light wave......

'Hmmm! Got an idea! ’

Wu Bin couldn't help but snap his fingers, and then began to use a spectrometer to measure the minimum deflection angle of the monochromatic light wave corresponding to the Mitsubishi mirror.

As long as there is an idea, the experimental questions are still relatively easy to follow, although the process is a little difficult, but in the end, Wu Bin still spent two hours to complete the final third question.

……

When he returned to the hotel after the exam, Wu Bin saw the expected scene, and the hall was full of "wandering" candidates with gloomy faces.

Because he still thinks he is very strong in the experimental questions, and this is a topic that even he thinks is sassy, even if it is a group of heavenly pride who can enter the national competition, it is estimated that he will be disgusted.

The meeting point that the Huhai team said was on the second floor, and when Wu Bin walked up, he found that almost everyone else was already there, and they were scolding their mothers in a group at the moment.

"It's good to say that the experiment questions are warm???

"Needless to say, this question is really showing, my scalp is numb, I spent an hour and a half just looking for the crosshairs reflected back from the plane mirror in the telescope! There's no time to do it later. ”

"I also adjusted the dimming axis and the rotating shaft of the instrument vertically for a long time, wow...... It's really a big tune. ”

……

This kind of complaint is actually quite rare to hear, because the unwritten rule is not to talk about the content of the exam after the exam.

But it is estimated that the question of this experiment is too angry, so everyone is crazy to complain.

"Yo, Wu Shen is here, isn't the experiment exciting?" Lu Xuange shouted as soon as he saw Wu Bin.

"Exciting, indeed exciting." Wu Bin nodded.

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

So until dinner time, almost everyone was complaining about this experimental question, although Wu Bin felt that some of the details they complained about were actually reminded in the title, but they didn't pay attention to it, but at this time it was better not to talk about it.

After all, many times if you don't see through it, you are still good friends.

But no matter how painful the process is and how unacceptable the result is, this time the National High School Physics Competition, here, is finally over completely, and the rest is only waiting for the announcement of scores and rankings.

Wu Bin didn't eat with everyone for dinner, his two teachers came all the way, so he naturally wanted to accompany him.

It was also quite interesting to talk to the two teachers about the theory test and the experimental questions during the meal.

……

Before the announcement was made the next morning, the competition committee organized the students to visit the Hongyan Link, including Hongyan Village, Bai Mansion, and Dregs Cave, which enhanced the party spirit of a wave of students.

It's just that the teacher can obviously feel that the students are not interested in visiting, so they went back to the hotel after the tour early.

After eating a buffet, 4 p.m., the score ...... It's finally announced.

"Mom hi...... It's a bit of a shame to check. ”

The Shanghai team gathered together early, and Zhao Kehan, who was standing next to Wu Bin, was sweating all over his head.

"What's not to dare to do, stretching out your head is a knife, shrinking your head is also a knife, it's better to be happy." After Lu Xuange finished speaking, he checked and divided.

"!!"

Just when everyone was extremely entangled, Lu Xuange suddenly burst out with a foul language.

"What's the matter, you're on the national team? So excited. Xiao Songyang glanced at Lu Xuange and asked.

"I can't make it to the national team, I haven't seen it yet...... But Wu Shen entered, he was the first! , I don't know what to say except for the groove! ”

Lu Xuange's words made everyone stunned, and even Wei Tianshuo stood up in fright, and hurriedly looked at the ranking list that had just been announced with his classmates.

Province: Huhai, School Name: Xiaguang Middle School, Student Name: Wu Bin, Gender: Male Grade: Senior 3, Theory: 270, Experiment: 79 Total Score: 349 Rank: 1

Province: Hubei, School Name: No. 1 High School Affiliated to China Normal University, Student Name: Gong Chengwei, Gender: Male, Grade: Senior 2, Theory: 265, Experiment: 75 Total Score: 340 Rank: 2

Province: Hunan, School Name: Yali Middle School, Student Name: Zhang Fu, Gender: Male, Grade: Senior 3, Theory: 255, Experiment: 70 Total Score: 325 Rank: 3

……

"I'm ...... Wu Shen is awesome! After Zhao Kehan finished reading, he slapped Wu Bin hard and shouted.

"It's a horse! It's like the monster in the second, and he threw off the third place by more than 12 points! What's so ...... My knees are a little weak. ”

"To tell the truth, I really didn't expect this, although I knew that Wu Shen was powerful, but I really didn't expect it...... Wu God! Wu God! Let me hug your legs! ”

……

After checking the scores, the rest area on the second floor was simply chaotic, and Wu Bin, as the party concerned, was actually in a very delicate mood at this time.

I was deducted 10 points for my theory questions??? ’

You must know that he is confident that he can get a full score after doing it, and now he is a batch of uncomfortable!
