Electromagnetic waves are transverse waves. They consist of traveling electric and magnetic fields which oscillate periodically. What angle does the electric field make with the magnetic field in an electromagnetic wave?

90°

Explanation:

In electromagnetic waves the angle made by the electric and magnetic fields is 90°.

Transverse waves are waves that are perpendicular to the direction of propagation. They differ from longitudinal waves in which their oscillation is parallel to the direction of the wave.

Electromagnetic waves are specially classified as transverse waves. The angle between the vibration of the electric and magnetic field is 90° Electromagnetic waves do not require any sort of material medium to propagate.
