We know that electric and magnetic field are associated with electromagnetic wave travelling in vaccum or some medium. Electric and magnetic fields

A

remain constant

B

are mutually perpendicular

C

are perpendicular to the direction of travel of light

D

have same average value

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
We know that both the fields and direction of propagation are mutually perpendicular to one another. We already know that fields vary sinusoidally according to time and hence their average values remain zero. Therefore, we can say that both the fields have same average value.
