A beam of natural light is incident on an air-glass

zvonat [6]

Answer:

The degree of polarization of the reflected light $74.6^{\circ}$

Solution:

As per the question:

Refractive index, $\mu = 1.5$

Angle of incidence, $\angle i = 40^{\circ}$

Now,

To calculate the degree of polarization:

We know according to the laws of reflection, angle of incidence and angle of reflection are equal.

$\angle i = \angle r = 40^{\circ}$

Also, from Brewster law:

$\mu = \frac{sin p}{sin r}$

$\musin r = sin p$

$p = sin^{- 1}{1.5\times sin 40^{\circ}} = 74.6^{\circ}$
