Question:

The Brewster's angle for glass of refractive index 1.5 is

Options:

57.3°

45°

60°

67.3°

Correct Answer:

57.3°

Explanation:

The correct answer is option (1) : 57.3°

Brewster's angle for glass of refractive index 1.5 is

$i=tan^{-1}(\mu )$

$⇒i=tan^{-1}(1.5)$

$⇒i=56.3°$

⇒ The answer coming out is most close to option 1 i.e. 57.3°
