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?
Answer & explanation
Correct answer: option 4
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
