Question

For a beam of light in air (n = 1) reflecting off glass (n = 1.5), what is Brewster's angle to the nearest degree?

Answer 1

Answer: 56°

Step-by-step explanation:

Brewster's angle refers to the angle at the point where light of a certain polarization passes through a transparent dielectric surface and is transmitted perfectly such that no reflection is made.

The formula is;

`= Tan^(-1) ((n_(2) )/(n_(1)) )`

`= Tan^(-1) ((1.5 )/(1) )`

= 56.30993247

= 56°
