Question

In a plane electromagnetic wave, the electric field oscillates sinusoidally at a frequency of 2.5 × 1 0 10 H z and amplitude 480 V m - 1 . The amplitude of the oscillating magnetic field will be, 1.52 × 10 - 8 Wb m - 2, 1.52 × 10 - 7 Wb m - 2, 1.6 × 10 - 6 Wb m - 2, 1.6 × 10 - 7 Wb m - 2

MARKS App · Accepted Answer

If c is the speed of light or electromagnetic wave then the amplitude of electric and magnetic fields are related as, B 0 = E 0 c B 0 = 480 3 × 1 0 8 = 1.6 × 1 0 - 6 Wb m - 2
