Total Internal Reflection Simulation
Medium Properties
Light Source
When light travels from a denser medium to a rarer medium, it bends away from the normal according to n₁·sinθ₁ = n₂·sinθ₂. At the critical angle (θ_c = sin⁻¹(n₁/n₂)), the refracted ray grazes the surface (90° refraction). Beyond this angle, total internal reflection occurs.
Current critical angle: 41.81°
Status: Partial reflection and refraction
