Question:
A radar system produces pulses consisting of exactly 100 full cycles of a sinusoidal 72.5-GHz electromagnetic wave. The average power while the transmitter is on is 66.0 MW, and the waves are confined to a beam 22.4 cm in diameter. Find
(a) the peak electric field,
(b) the wavelength,
(c) the total energy in one pulse, and
(d) the total momentum in one pulse.
(e) If the transmitter produces 945 pulses each second, what’s its average power output?
