Assume a point source emits 0.5 watts of radio waves that has frequency of 1.8 GHz. (a) Find the wavelength in meters and energy in eV of this radio waves? A radio wave is a transverse wave of oscillating electric and magnetic fields. (b) What are the amplitudes of the electric and magnetic fields at a distance of 10 cm away from the point source? You may have to use these parameters: speed of light = 3x108 m/s, e = 1.6 x 10-19 C, permittivity constant = 8.85 x 10-12 C2/ N.m², permeability constant 26-10-6TA
