Question

A ray of light in air is incident on a glass plate at 45°
The refractive index of glass is 1.5. What is angle of
refraction?
.​

Answer 1

Answer:

The angle of refraction of the ray of light is 26.22 degrees. So, the angle of refraction of the ray of light is 26.22 degrees

Answer 2

Answer:

Explanation:

refractive index = sin i / sin r

here i = 45 so,

1.5= sin 45 /sin r

then sin r = root 2 /3

so r = sin inverse root 2 /3
