Class 11 NEET Physics Waves Questions Questions

Question : 5 of 96

Marks: +1, -0

Both reflected and transmitted light are perfectly polarized with angles of reflection and refraction close to $60^{\circ}$ and $30^{\circ}$ , respectively
Transmitted light is completely polarized with angle of refraction close to $30^{\circ}$
Reflected light is completely polarized and the angle of reflection is close to $60^{\circ}$
Reflected light is partially polarized and the angle of reflection is close to $30^{\circ}$

Solution: 👈: Video Solution

Using Brewster law

\mu=\tan\theta\rho

\Rightarrow 1.73=\tan\theta_P

\Rightarrow\sqrt{3}=\tan\theta_p

\Rightarrow\theta p=60^{\circ}

At this polarising angle, reflected light is perfectly polarized and transmitted light is partially polarised.
