1.	For a glass plate as a polariser with refractive index 1.633, calculate the angle of incidence at which light is polarised.
Answer» Given: μ = 1.633 To find: Polarising angle (i_p) Formula: μ = tan i_p Calculation: From formula we get, i_p = tan_-1 (1.633) \(\therefore\) i_p = 58°31' The angle of incidence at which light is polarised is 58°31'.

For a glass plate as a polariser with refractive index 1.633, calculate the angle of incidence at which light is polarised.

Answer»

Given: μ = 1.633

To find: Polarising angle (i_p)

Formula: μ = tan i_p

Calculation: From formula we get,

i_p = tan_-1 (1.633)

\(\therefore\) i_p = 58°31'

The angle of incidence at which light is polarised is 58°31'.
