The magnetic field amplitude of an elect...

The magnetic field amplitude of an electromagnetic wave is `2 xx 10^(-7)T`. Its' electirc field amplitude if the wave is traveling in free space is

A

`6 V//m`

B

`60 V//m`

C

`10//6 V//m`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
Speed of light, `c = (E_(0))/(B_(0)) rArr E_(0) = B_(0)c`
Given `B_(0) = 2 xx 10^(-17) xx 3 xx 10^(8) = 60 T m//s = 60 v//m`
