A dish antenna with a diameter of 20.0 m receives (at normal incidence) a radio signal from a distant source. The radio signal is a continuous sinusoidal wave with amplitude Emax = 0.20 mV/m. Assume the %3D antenna absorbs all the radiation that falls on the dish. What is the power received by the antenna? 2.25 10^-6 O 2.67 10^-5 3.65 10^-5 4.65 10^-5
