When an unpolarised light is incident at an angle of \(60^{\circ}\) on a transparent medium from air, the reflected ray is completely polarised. The angle of refraction in the medium is
1 \(30^{\circ}\)
2 \(45^{\circ}\)
3 \(90^{\circ}\)
4 \(60^{\circ}\)
Explanation:
As the ray of light is incident at polarising angle \(\left(i_{p}\right)\), so the reflected and refracted rays will be perpendicular to each other. If ' \(r\) ' is the angle of refraction, then using Brewster's law \(i_{P}+r=90^{\circ}\) \(\Rightarrow r=90^{\circ}-i_{p}\) Here, \(i_{p}=60^{\circ}\) \(\Rightarrow r=90^{\circ}-60^{\circ}=30^{\circ}\)
