List of top Physics Questions on Polarization

Which of the following statement is incorrect about Bohr's model of atom?

An unpolarized light of certain intensity passes through a combination of two polarizers whose transmission axes are at \(30^\circ\) and \(90^\circ\), respectively, with respect to the horizontal axis. A third polarizer with its transmission axis at \(60^\circ\) with the horizontal axis is placed between the two existing polarizers. The ratio of the output intensities with and without the third polarizer is:

An unpolarized light is incident on the plane interface of air-dielectric medium shown in figure. If the incident angle is equal to Brewster angle, identify the expression representing reflected wave.

A polaroid sheet is rotated between two crossed polarizers. The intensity of transmitted light would be maximum, when the angle between the axes of the first polarizer and the polaroid sheet is

The intensity of transmitted light when a polaroid sheet, placed between two crossed polaroids at \(22.5^\circ\) from the polarization axis of one of the polaroids (\(I_0\) is the intensity of polarised light after passing through the first polaroid):

In the given circuit, the current in resistance R3 is :
