This simulation uses Snell’s Law: n₁sin(θ₁) = n₂sin(θ₂) to calculate accurate light refraction. Higher refractive indices (n) cause more bending of light towards the normal. Try different materials to see the effects, including Total Internal Reflection (TIR)!
模擬器使用斯涅爾定律計算光線折射。折射率 (n) 越高，光線偏折越明顯。嘗試不同材質以觀察全內反射 (TIR) 等現象！
