In an electromagnetic wave in free space...

In an electromagnetic wave in free space the root mean square value of the electric field is `E_(rms)=6 V//m`. The peak value of the magnetic field is

A

`2.83xx10^(-8) T`

B

`0.70xx10^(-8) T`

C

`4.23xx10^(-8) T`

D

`1.41xx10^(-8) T`

Text Solution

Verified by Experts

The correct Answer is:
A
`E_(0)=sqrt(2)E_(rms)=6sqrt(2) V//m`
`E_(0)=CB_(0)`
`B_(0)=(E_(0))/C=(6sqrt(2))/(3xx10^(8))=2.83xx10^(-8) T`
