In our pre-experiment, I got the image. It’s obvious that the order of diffraction from the top down is 3,2,1,0,-1,-2,-3, the background of optics is so easy.
Then I have to get the light intensity of the diffraction spot, denote as I(n),n in -3 to 3(in this experiment).
How to think about the problem and manipulate the processes with Mathematica? Thanks so much!
You can also just analyze this simple case.
