(a) An e.m. wave is travelling in a medium with a velocity `vecv=vhati`.Draw a sketch showing the propagation of the e.m. wave, indicating the direction of the oscillating electric and magentic fields.
(b) How are the magnitudes of the electric and magnetic fields related to the velocity of the e.m. wave?
