The refractive index of a medium is equal to the tangent of the polarizing angle. This is known as:

An unpolarized light beam travelling in air is incident on a medium of refractive index $1.73$ at Brewster's angle. Then

An unpolarized light is incident from air on the boundary of a denser medium having refractive index $\mu$ at polarizing angle $i_p$. Which of the following is correct?

At what angle should an unpolarised beam be incident on a crystal of $\mu = \sqrt{3}$,so that the reflected beam is polarised (in $^{\circ}$)?

Unpolarised red light is incident on the surface of a lake at an incident angle $\theta_{R}$. An observer seeing the light reflected from the water surface through a polariser notices that on rotating the polariser,the intensity of light drops to zero at a certain orientation. The red light is replaced by unpolarised blue light. The observer sees the same effect with reflected blue light at an incident angle $\theta_{B}$. Then,

Unpolarized light of intensity $I_0$ is incident on the surface of a block of glass at Brewster's angle. In that case,which one of the following statements is true?
