Q116 / 180 · NEET 2020 (Phase 1) · Physics

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)

Correct answer
A
$1 : 1$
B
$1 : c$
C
$1 : c^{2}$
D
$c : 1$

Solution

In EMW, electric field and magnetic field have same energy density and same intensities.

Hence, the correct answer is option: 'A'.
