Answer 1

Snell's Law:

The ratio of the $\sf{Sine}$ of the Angle of Incidence to the $\sf{Sine}$ of the Angle of Refraction for a given pair of media, is constant.

This constant is known as Refractive Index.

$\boxed{ \sf{ \dfrac{ \sin(i) }{ \sin(r) } = \dfrac{ n_{2}}{ n_{1} } = \dfrac{Real \: Depth}{Apparent \: Depth}=n=\mu} }$
