Question

State the Snell's laws of refraction of light.1​

Answer 1

Answer:

n =

$n = \frac{r}{i}$

It's known as Snell laws

Answer 2

Answer:

Snell's Law states that the ratio of the angle of incidence to the angle of refraction of a wave as it travels through a boundary between two media is a constant termed the refractive index.

Explanation:

The ratio of the sine of the angle of incidence to the ratio of sine of angle of refraction is a constant for a light of a specified colour and for the specified pair of media.
