A satellite 555 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.
Part A. What is the intensity of these waves as they reach a receiver at the surface of the earth directly below the satellite?
I =
W/m2
Part B. What is the amplitude of the electric field at the receiver?
Emax = N/C
Part C. What is the amplitude of the magnetic field at the receiver?
Bmax = T
Part D. If the receiver has a totally absorbing panel measuring 20.0 cm by 35.0 cm oriented with its plane perpendicular to the direction the waves travel, what average force do these waves exert on the panel?
F =
N
Part E. Is this force large enough to cause significant effects?
a. yes
b. no
