Задача 40555.

Towards monochromatic light with a wavelength of 0.6 microns is a plane-parallel glass plate 0.1 mm thick. Light falls on the plate normal. As far as the plate thickness to be increased, the optical path length changed to lambda / 2, if the refractive index of the plate 1.5?

Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
