plzz answer me quickly

Answer 1

Refraction of light is defined as the phenomena of bending of light towards when it enters another media.

Snell's Law:

Sin I/Sin R = n21

It states that the speed of light in first and second medium is proportion to sin of angle of incidence and sin of angle of refraction.

It is denoted by mew
