The correct answer is:
\( 33^{\circ} \)
Given, polarising angle of glass, \( i_{p}=57^{\circ} \)
We know that, when the light is incident at polarising angle then reflected and refracted rays are at right angles to each
other.
Therefore,
\[
r=90^{\circ}-i_{p}=90-57=33^{\circ}
\]
Therefore, angle of refraction is \( 33^{\circ} \).
