A plane electromagnetic wave travels in ...

A plane electromagnetic wave travels in free space along the `x-`direction. The electric field component of the wave at a particular point of space and time is `E=6Vm^(-1)` along `y-`direction. Its corresponding magnetic field component, `B` would be:

A

`6xx10^(-8)T ` along x direction

B

`2xx10^(-8)` along - direction

C

`2xx10^(-8)T` along z - direction

D

`6xx10^(-8)T ` along z direction

Text Solution

Verified by Experts

The correct Answer is:
C
`E/B=c implies B=(6)/(3xx108)=2xx10^(-8)T`
Direction of magnetic field will be perpendicular to both electric field and direction of propagation of wave
