Задача 50193.

Electromagnetic radiation falls on a substance, the frequency of which is 1.5 times higher than the frequency corresponding to the red border of the photoelectric effect for this substance. In this case, the delaying potential difference is 1.25 V. Find the work function of the electrons from the substance and the momentum of the incident photons.

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 will try to help.
