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

Options

A. `E_(x') B_(y)`
B. `E_(y)'B_(z)`
C. `b_(X')E_(y)`
D. `E_(z') B_(y)`

Answer

B, D

Explanation

As electric and magnetic field vector E and B are perpendicular to each other as well as perpendicular to the direction of propagation of electromagnetic wave.
Here in the question electromagnetic wave is propagating along x-direction .So, electric and magnetic field vector should have either y- direction or z- direction.
