A dish antenna having a diameter of 18.0 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 = 0.800 V/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 this antenna? W/m2 (c) What is the power received by the antenna? w (d) What force is exerted by the radio waves on the antenna? N
