Q. An Electromagnetic Wave has
A) Electric vector only
B) Magnetic vector only
C) Electric and Magnetic vector Perpendicular to each other
D) Neither the Electric vector nor the Magnetic vector
Explanation
(c) A changing electric field produces a changing magnetic field and $vice - versa\ $which gives rise to a transverse wave known as Electromagnetic Wave. The time varying electric and magnetic fields are mutually perpendicular to each other and also perpendicular to the direction of propagation of this wave.
