Задача 40181.

A layer of a transparent substance with a refractive index of 1.3 is deposited on a glass plate. A normally parallel beam of monochromatic light with a wavelength of 640 nm falls on the plate. What is the minimum thickness of the layer that the reflected rays should be attenuated as much as possible as a result of interference?

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