📊 Snell's Law Formula
n₁sin(θ₁) = n₂sin(θ₂)
Where n₁,n₂ are refractive indices, θ₁,θ₂ are incident and refracted angles
Refracted Angle:
-
Refractive Index:
-
Critical Angle:

💡 Tips & Information
- Light bends toward normal when entering denser medium
- Light bends away from normal when entering less dense medium
- Critical angle: θc = arcsin(n₂/n₁) where n₁ > n₂
- Total internal reflection occurs when θ > θc
- Air: n ≈ 1.0, Water: n ≈ 1.33, Glass: n ≈ 1.5
