What changes during the polarisation of light?

A

Frequency

B

Wavelength

C

Phase

D

Intensity

Text Solution

Verified by Experts

The correct Answer is:
D
Intensity of light in its wave form depend on the amplitude of longitudinal wave. Unpolarised light has high intensity since it has both components. When unpolarised light, polarised it has components in a certain direction perpendicular to the direction of propagation so their intensity is always low.
