List of top Physics Questions on Polarisation asked in KCET

An unpolarised light of intensity I is passed through two polaroids kept one after the other with their planes parallel to each other. The intensity of light emerging from second polaroid is \(\frac{I}{4}\). The angle between the pass axes of the polaroids is

Which of the statements is false in the case of polar molecules?

Three polaroid sheets $P_1, P_2$ and $P_3$ are kept parallel to each other such that the angle between pass axes of $P_1$ and $P_2$ is $45^\circ$ and that between $P_2$ and $P_3$ is $45^\circ$. If unpolarised beam of light of intensity $128 Wm^{-2}$ is incident on $P_1$. What is the intensity of light coming out of $P_3$?

The polarizing angle of glass is $57^\circ$. A ray of light which is incident at this angle will have an angle of refraction as

An unpolarised beam of intensity $I_0$ is incident on a pair of nicols making an angle of $60^\circ$ with each other. The intensity of light emerging from the pair is
