The polarizing angle of glass is 57°. A ray of light which is incident at this angle will have an angle of refraction as

Options

A. `33^(@)`
B. `38^(@)`
C. `25^(@)`
D. `43^(@)`

Answer

A

Explanation

As the ray of light incident at gass at polarizing angle `(i_(p))` so the reflected and reflected rays are perpendicular to each other .
If r is the angle of refraction , then
` i_(p) + r = 90^(@)`
` r = 90^(@) - i_(p)`
Here , `i_(p) = 57^(@)`
` :. " " r = 90^(@) - 57^(@) = 33^(@)`
