A dish antenna having a diameter of 20.0 m receives (at normal incidence) a radio signal from a distant source, as shown in Figure P34.51. The radio signal is a continuous sinusoidal wave with amplitude Emax= 0.200 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?
(b) What is the intensity of the radiation received by this antenna?
(c) What is the power received by the antenna?
(d) What force is exerted by the radio waves on the antenna?
