When a Polaroid is rotated in the path of unpolarised light, the intensity of light coming out from Polaroid remains undiminished because unpolarised light have vibrations in all possible planes. While a Polaroid when rotated in path of plane polarized light, its intensity will vary form maximum to minimum. Thus, using Polaroid, unpolarised light and polarized light can be distinguished from each other.
