Snell's Law and Refraction

Refraction is the bending of light as it passes from one transparent substance into another. This bending occurs because light travels at different speeds in different materials.

• n1, n2: The refractive indices of the two materials.
• θ1: The angle of incidence.
• θ2: The angle of refraction.

Formula: n1 sin(θ1) = n2 sin(θ2)

Common indices: Vacuum (1.0), Air (1.0003), Water (1.33), Glass (1.5), Diamond (2.42).
