Snell's Law Calculator
Calculate refraction using Snell's Law: n₁ sinθ₁ = n₂ sinθ₂. Compute refraction angle, incident angle, or refractive index. Features angle units (degrees/radians), refractive indices for common materials, critical angle calculation, and total internal reflection detection. Perfect for physics students studying optics.
