Question

When an unpolarized light falls at a particular angle on a glass plate (placed in air), it is observed that the reflected beam is linearly polarized. The angle of refracted beam with respect to the normal is ______.

$(t a n^{- 1} (1.52) = 57.7 °,$ refractive indices of air and glass are 1.00 and 1.52, respectively.) [2026]

$\tan i = \frac{μ_{2}}{μ_{1}} = \frac{μ_{g}}{μ_{a}}$

$\tan i = 1.52$

$i = 57.7 °$

$r = 90 ° - i$

$r = 32.3 °$

Solution

1 $36 . 3^{\circ}$

2 $32.3 °$

3 $39.6 °$

4 $42.6 °$
