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 vacuum

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 amplitude of magnetic field and electric field for an electromagnetic wave propagating in vacuum are related as
`E_(0)=B_(0)c`
where c is the speed of light in vacuum
`therefore" "(B_(0))/(E_(0))=(1)/(c)`
