Question

The ratio of contributions made by the electric field and magnetic field components to the intensity of an EM wave is [NCERT Exemplar]
(a) c : 1
(6) c² : 1
(c) 1 : 1
(d) √c : 1

Answer 1

Answer:

It means the ratio of contributions by the electric field and magnetic field components to the intensity of an electromagnetic wave is 1:1. When the incident EM wave is completely absorbed by a surface, it delivers energy u and momentum u/c to the surface.
