A dish antenna with a diameter of 25.2 m receives (at normal incidence) a radio signal from a distant source, as shown in the figure below. The radio signal is a continuous sinusoidal wave with amplitude Emax = 0.28 µV/m. Assume the antenna absorbs all the radiation that falls on the dish. (a) What is the amplitude of the magnetic field in this wave? T (b) What is the intensity of the radiation received by the antenna? W/m2 (c) What is the power received by the antenna?
