Formula description

Snell`s Law

When light waves propagate from one medium to another medium with a different refractive index, refraction occurs.
The incident angle and reflection angle will satisfy the following formula:


n1:The refractive index of medium 1.
n2: The refractive index of medium 2.
θ1:The angle between the incident light wave and the interface normal.
θ2:The angle between the refracted light wave and the interface normal.
