Question

un polarised light is incident on a plane glass.
surface. What should be the angle of incidence
so that the reflected and retracted rays.
are prependicular to each other​

Answer 1

Answer:

56.3

Step-by-step explanation:

refractive index of glass =1.5

we will consider the refractive index to be \mu

if \i_p is the polarizing angle

then,

The reflected ray and the refracted ray will be perpendicular to each other when the angle of incidence = polarizing angle i.e. i_p

according to this-

$\mu = \tan(i_p) \\ 1.5 = \tan(i_p) \\ tan ^{ - 1} (1.5) = i_p\\ \\ 56.3 = i_p$
