Задача 40257.

Between the two plane-parallel plates put a very thin wire disposed parallel to the line of contact between the plates and located at a distance L of 75 mm from it. In the resulting air wedge normal to its surface falls monochromatic light with a wavelength of 0.5 microns, in reflected light on the upper plate visible interference fringes. Determine the diameter d of delays, if over 30 mm there are 16 bands of light.

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