In a plane electromagnetic wave, the electric field oscillates sinusoidally at a frequency of2.5×1010 Hzand amplitude480 V m-1. The amplitude of the oscillating magnetic field will be

Options:

Answer:
C
Solution:

Ifcis the speed of light or electromagnetic wave then the amplitude of electric and magnetic fields are related as,

B0=E0c

B0=4803×108=1.6×10-6 Wb m-2
