Задача 40451.

The diffraction grating with a length of L = 3 cm has a period d = 3 μm. What is its resolution in the second order? What is the difference in distinguishable wavelengths for green light rays (lambda = 540 nm) in this order? What is the maximum order of the spectrum and the angle (phi) of the deviation of the rays corresponding to the largest diffraction maximum?

A detailed solution with a brief record of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have questions about the solution, write. I will try to help.
