- #2The ratio of contributions made by the electric field and magnetic field components to the intensity of an electromagnetic wave is : (c = speed of electromagnetic waves)
(A)c : 1
(B)1 : 1
(C)1 : c
(D) `` 1 : c^2 ``
digAnsr: BAns : In an electromagnetic wave, half of the intensity is provided by the electric field and half by the magnetic field. Hence, required ratio should be `` 1 : 1 ``
