Задача 40026.

In vacuum, a plane electromagnetic wave propagates along the x axis. The amplitude of the electric field of the wave is 50 mV / m. Determine the intensity of wave I, that is, the average energy passing through a unit of surface per unit of time.

A detailed solution with a brief record of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have questions about the solution, write. I will try to help.
