Question 393: Wave Optics

Question

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

Accepted Answer

Using Brewster law
$$\begin{aligned}
&\begin{aligned}
& \mu=	an 	heta_p \
& \Rightarrow 1.73=	an 	heta_p \
& \Rightarrow \sqrt{3}=	an 	heta_p \
& \Rightarrow 	heta_p=60^{\circ}
\end{aligned}\
&	ext { At this polarising angle, reflected light is perfectly polarized and transmitted light is partially polarised. }
\end{aligned}$$

Answer

Both reflected and transmitted light are perfectly polarized with angles of reflection and refraction close to $60^{\circ}$ and $30^{\circ}$, respectively

Answer

Transmitted light is completely polarized with angle of refraction close to $30^{\circ}$

Answer

Reflected light is completely polarized and the angle of reflection is close to $60^{\circ}$

Answer

Reflected light is partially polarized and the angle of reflection is close to $30^{\circ}$
