## Snell's Law
Snell's law describes how light bends when passing between media with different refractive indices.
### Formula
**n1 * sin(theta1) = n2 * sin(theta2)**
Light bends toward the normal when entering a denser medium (higher n) and away from the normal when entering a less dense medium.

Exemple Résolu
Light enters glass (n=1.5) from air (n=1) at 30 degrees.
- n1*sin(theta1) = n2*sin(theta2)
- 1*sin(30°) = 1.5*sin(theta2)
- 0.5 = 1.5*sin(theta2)
- sin(theta2) = 0.333
- theta2 = 19.47°
