A plane electromagnetic wave propagating along x - direction can have the following pairs of vec(E ) and vec(B).

Answer»

`E_(X), B_(y)`
`E_(y),B_(z)`
`B_(x),E_(y)`
`E_(z),B_(y)`

SOLUTION :In electromagnetic waves electric field VECTOR `vec(E )` and magnetic field vector `vec(B)` are perpendicular to each other ALSO they are perpendicular to DIRECTION of propagation.
In given question (from data) electromagnetic waves propagate in x - direction, hence, electric field and magnetic field vector can be in y - direction or z - direction. Hence, option (B) and (D) are correct.
