Question

What is the Brewster angle for air to glass transition? (Refractive index of glass = 1.5.)

Answer 1

Given: the refractive index of the glass is $\mu =1.5$

The Brewster angle for the air to glass transition is given by:

$tan\theta =\mu$

$\theta =ta{n}^{-1}\mu$

$\theta =ta{n}^{-1}1.5$

Brewster angle $\theta ={56.31}^o$
