Which of the following statement s regarding EM waves is are false a The ratio of electric field strength En to magnetic field strength Ho of a plane electromagnetic wave in vacuum has the dimensions of electric resistance and is always equal to one b The average value of electric field in a plane electromagnetic wave is independent of electric energy and has a constant non zero magnitude perpendicular to the direction of wave propagation c The frequency of oscillation of energy contained in a small volume through which an electromag netic wave is passing would be double the frequency of the wave d An electron released from rest in the path of a plane electromagnetic wave will start moving along the direction of wave propagation
