Radio waves of frequency 1.1 x 10^10 Hz are emitted from a radar antenna travelling in an eastward direction. At one instant the electric field at a given point has a magnitude of 0.60 V/m and points down. For the radiation at that instant calculate:
a) the wavelength.
b) the magnitude and direction of the magnetic field.
c) If the amplitude of the electric field component is 1.2 V/m, calculate the intensity of the wave.
