Which statement best describes light, whether polarized or unpolarized?

a. light in which the electric and magnetic vectors oscillate parallel to the direction of propagation of the wave
b. light in which the electric vector oscillates parallel and magnetic vector oscillates perpendicular to the direction of propagation of the wave
c. light in which the electric and magnetic vectors oscillate perpendicular to the direction of propagation of the wave
d. light in which the electric vector oscillates perpendicular and magnetic vector oscillates parallel to the direction of propagation of the wave

C. light in which the electric and magnetic vectors oscillate perpendicular to the direction of propagation of the wave

Explanation:

Light is an electromagnetic wave in which electric field vector and magnetic field vector both oscillates perpendicular to each other and also these two components are perpendicular to the propagation of wave.

As we know that the direction of velocity of wave is given by the formula

so here the velocity vector must be perpendicular to vector E and vector B

so here correct answer will be

C. light in which the electric and magnetic vectors oscillate perpendicular to the direction of propagation of the wave
