The ratio of amplitude of magnetic field to the amplitude of electric field of an electromagnetic wave propagating in vacuum is

Options

  1. Areciprocal of speed of light in vacuum
  2. Bthe speed of light in vacuum
  3. Cproportional to frequency of the electromagnetic wave
  4. Dinversely proportional to the frequency of the electromagnetic wave

Correct answer

A. reciprocal of speed of light in vacuum

Step-by-step solution

For an electromagnetic wave, Speed of electromagnetic wave, c= E₀ B₀ B₀ E₀ = 1 c = reciprocal of speed
