Task 40516.

Plane electromagnetic waves, the intensity of which is equal to 12 W / m2, is distributed in a vacuum. The oscillation frequency of wave 2 * 10 ^ 16 Hz. To determine the electromagnetic wave equation with numerical coefficients, initial conditions are randomly selected. In solving the problem, note that the mean square sine (or cosine) for the period is 0.5.
