Answer #1

fig. Refraction of light.

Let light incident on a interface at angle i and refracted by an angle r and V1(air) and V1(glass) are the speed of light in this two media.

Applying snells's law

where are refractive indexs of air and glass respectively.

(refractive index is the ratio of speed of light in vacuum and medium.)

therefore

Therefore angle of refraction is
