The 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)

Question

The 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: c2

Tardigrade Admin · Accepted Answer

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

Q. The 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)

c : 1

1 : 1

1 : c

$1 : c^{2}$

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 $1 : 1$
