Answer 2

Answer:

First of all...It's Snell's law...

It

Explanation:Snell's law states that the ratio of the sines of the angles of incidence and refraction is equivalent to the ratio of phase velocities in the two media, or equivalent to the reciprocal of the ratio of the indices of refraction:

{\displaystyle {\frac {\sin \theta _{2}}{\sin \theta _{1}}}={\frac {v_{2}}{v_{1}}}={\frac {n_{1}}{n_{2}}}} {\displaystyle {\frac {\sin \theta _{2}}{\sin \theta _{1}}}={\frac {v_{2}}{v_{1}}}={\frac {n_{1}}{n_{2}}}}

with each {\displaystyle \theta } \theta as the angle measured from the normal of the boundary, {\displaystyle v} v as the velocity of light in the respective medium (SI units are meters per second, or m/s), and {\displaystyle n} n as the refractive index (which is unitless) of the respective medium.
