When
red light in vacuum is incident at the polarizing angle on a certain
glass slab, the angle
of refraction is
|
Solution: Click For PDF Version (a)
It is found
experimentally that at the polarizing angle the sum of the angle of
refraction
That is
As
(b)
According to
Brewster’s law, polarizing angle, if light is incident from
air/vacuum, and the index of refraction
We thus find that the index of refraction for red light in glass is 1.61.

.
We have to find (a)
the index of refraction of the glass and
(b) the polarizing angle.
and the polarizing angle
is
.
,
we find
is
