A dish antenna with a diameter of 20.0 m receives (at normal incidence) a radio signal from a distant source, as shown in figure. The radio signal is a continuous sinusoidal wave with amplitude Emax = 0.20?V/m. Assume that the antenna absorbs all the radiation that falls on the dish.(a) What is the amplitude of the magnetic field in this wave?(b) What is the intensity of the radiation received by the antenna?(c) What is the power received by theantenna?
