Задача 40777.

In the quartz crystal plate cut parallel to the optical axis, normally incident light with a wavelength of 600 nm. The refractive indices of the ordinary and extraordinary n0 nc rays are n0 = 1,544, nc = 1,553. What should be the thickness of the plate, there was a shift to the phases of the rays on the n / 2?

Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
