Question

A satellite 595 km above the earth's surface transmits sinusoidal electromagnetic waves of frequency 92.6 MHz uniformly in all directions, with a power of 25.0 kW.

A- What is the intensity of these waves as they reach a receiver at the surface of the earth directly below the satellite?

B- What is the amplitude of the electric field at the receiver?

C- What is the amplitude of the magnetic field at the receiver?

D- If the receiver has a totally absorbing panel measuring 10.0 cm by 45.0 cm oriented with its plane perpendicular to the direction the waves travel, what average force do these waves exert on the panel?
