Snell's Law

Refraction of light n₁sinθ₁ = n₂sinθ₂

○Not Started
n₁ = 1.00n₂ = 1.50θ₁ = 40°θ₂ = 25.4°

Parameters

n1sin⁡ heta1=n2sin⁡ heta2n_1\sin\ heta_1 = n_2\sin\ heta_2

θ₂ = 25.4°

• Light pulses travel along the ray through the interface • Into a denser medium → the ray bends toward the normal • Above the critical angle, total internal reflection occurs
