The ratio of amplitude of magnetic field...

The ratio of amplitude of magnetic field to the amplitude of electric field for an electromagnetic wave propagating in vacumm is equal to

A

the speed of light in vaccum

B

reciprocal of speed of light in vacuum

C

the ratio of magnetic permeability to the electric susceptibility of vacuum

D

unity

Text Solution

Verified by Experts

The correct Answer is:
B
The ratio of amplitude of magnetic field to the amplitude of electric field for an electromagnetic wave propagating in vaccum is equal to the reciporcal of speed of light in vaccum.
i.e,`(B_(0))/(E_(0)) = 1/c`
