If the RMS value of electric field is given as 5 V/m, what will be the peak value of magnetic field component of the electromagnetic wave?

5.4 x 10-8 T 3.4 x 10-8 T 0.4 x 10-8 T 2.4 x 10-8 T

2.4 x 10-8 T

Epeak = Erms \(\sqrt { 2}\)  Epeak = 5 V/m \(\sqrt { 2}\) = 7.1 V/m Epeak/Bpeak = c  Bpeak = Epeak / c = (7.1 V/m)/(3 x 108 m/s)  = 2.35 T
