Question

Find the polarizing angle of a dense flint glass having an index of 1.768

Answer 1

In this case, Brewster's angle (also known as the polarization angle) is given by formula

$$\theta=\arctan{\frac {n_2}{n_1}} (1)$$

where n₂=1.78, n₁=1.00

Using (1) we got:

$$\theta=60°$$

Answer:

60°
