How are em waves produced by oscillating charges?

Draw a sketch of linearly polarized em waves propagating in the Z-direction.

Indiacte the direction of the oscillating electric and magnetic fields.               (3)

 

Explanation:

A charge oscillating with some frequency, produces an oscillating electric field in space, which in turn produces an oscillating magnetic field perpendicular to both the fields.                                                                                (1)

            (1) 

Directions of E and B are perpendicular to each other and also perpendicular to direction of propagation of em waves .                                 12+12
