A) electric vector only
B) magnetic vector only
C) electric and magnetic vectors perpendicular to each other
D) neither the electric vector nor the magnetic vector
Correct Answer: C
Solution :
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.
