Задача 60191.

A parallel stream of electrons moving at the same speed falls normally onto a diaphragm with a narrow rectangular slit of width a = 1.0 μm. Determine the speed of these electrons if on the screen located at a distance of l = 50 cm from the slit, the width of the central diffraction maximum is 0.36 mm.

Detailed solution with a brief record of the conditions, formulas and laws used in the solution, derivation of the calculation formula and answer.
