In a plane electromagnetic wave travelling in free space, the electric field component oscillates sinusoidally at a frequency of 2.0 × 10^10 Hz and amplitude 48 V m^–1. Then the amplitude of oscillating magnetic field is (Speed of light in free space = 3 × 10^8 m s^–1)

V= E/B

for free space v=c

Putting all values in MKS (c=3 × 10^8, E=48 ) we get B=1.6 × 10^–7 Tesla
