A commercial aircraft recieves a homing radio signal with an intensity of 12 μW/m2 when it is 11 km from the transmitter.
a) What is the magnitude of the Poynting vector from the electromagnetic wave of this signal?
b) Assuming that the aircraft reflects all of the signal back along its path, what is the radiation pressure on the aircraft?
c) What is the amplitude of the electric component of the signal?
d) What is the amplitude of the magnetic component of the signal?
e) Assuming the transmitter radiates uniformly over a hemisphere, what is its transmission power?
