A plane electromagnectic wave propagating along x-direction can have the following pairs of `E` and `B`.

A

`E_x,B_y`

B

`E_y,B_z`

C

`B_x,E_y`

D

`E_z,B_y`

Text Solution

Verified by Experts

The correct Answer is:
(b,d)
As electric and magnetic field vectors `vecE and vecB` are `bot r` to each other as well as `bot r` to the direction of
propagation of em wave, hence option (b) and (d) are correct.
