In electromagnetic waves the ratio of amplitudes of electric field and magnetic field is equal to

In electromagnetic waves, the ratio of amplitudes of the electric field and the magnetic field is equal to the velocity of the electromagnetic waves in free space.

(E/ B0) = c

B0 / E0 = 1 / c

Where,

E= Electric field

B= Magnetic field

c = Velocity

  1. This relation E/B =c implies that the amplitude of the electric field E is 10^8 times greater than the amplitude of the magnetic field! Why is it so?
