List of top Physics Questions on Polarisation asked in KEAM

The primary purpose of using polaroids in sunglasses is to
The intensity of the transmitted light after passing through a first polaroid $P_1$ is $I_0$. If the second polaroid $P_2$ is rotated through an angle of $45^\circ$ with respect to $P_1$, then the change in the intensity of the transmitted light after passing through the second polaroid is
Plane polarized light can be produced by the phenomenon of
The Brewster's angle \( i_B \) for any interface should lie between
The reflected ray is completely polarized for certain angle of incidence in a transparent medium. If the angle of refraction is \(30^\circ\), then the refractive index of the medium is
The Brewster's angle for air to water interface is
If a ray of light is incident at a glass surface at the Brewster’s angle of \(60^\circ\), then the angle of refraction inside glass is
The polarising angle for a medium is found to be \( 60^\circ \). The critical angle of the medium is
