Q1.

Let the speed of light in a medium be $V$ and the polarising angle be $i_p$. If $C$ is the speed of light in vacuum,what is the relation between them?

(A)

$V=C \cos(i_p)$

(B)

$V \cos(i_p) = C \sin(i_p)$

(C)

$C = V \cot(i_p)$

(D)

$V \sin(i_p) = C \cos(i_p)$

Q2.

The polarising angle of a transparent medium is $\theta$. Let the speed of light in the medium be $v$. Then the relation between $\theta$ and $v$ is [where $c$ is the velocity of light in air].

(A)

$\theta=\sin ^{-1}\left(\frac{v}{c}\right)$

(B)

$\theta=\tan ^{-1}\left(\frac{v}{c}\right)$

(C)

$\theta=\cot ^{-1}\left(\frac{v}{c}\right)$

(D)

$\theta=\cos ^{-1}\left(\frac{v}{c}\right)$
