Find the minimum critical angle

Find the minimum critical angle at which total internal reflection occurs when light is emitted from a medium into air.

Snell's Law

We use Snell's law to calculate the angle of emergence (angle of deviation) from the angle of incidence in air to the medium.

Snell's Law: Part 2 (Angle of Incidence from a Medium to Air)

We use Snell's law to calculate the angle of refraction (the angle between the incident angle in the medium and the angle of emergence into air).
