A plane electromagnetic wave travels in vacuum along y-direction. What can you say about the direction of electric and magnetic field vectors?

A

`E_(x),B_(y)`

B

`E_(2),B_(x)`

C

`E_(y),B_(x)`

D

`E_(y),B_(2)`

Text Solution

Verified by Experts

The correct choice is (2).
The direction of wave motion is the direction of cross product `vec Cxx vecB`
`:. vecExxvecB` must be along y-axis
