Light – Reflection and Refraction — Key Formulas
| Formula | Expression |
|---|---|
| Law of reflection | Angle of incidence = angle of reflection (∠i = ∠r) |
| Mirror formula | 1/f = 1/v + 1/u; f = R/2 (R = radius of curvature) |
| Magnification (mirror) | m = h'/h = -v/u (- means inverted) |
| Snell's law | n₁sin(θ₁) = n₂sin(θ₂); n = c/v |
| Lens formula | 1/f = 1/v + 1/u (same as mirror) |
| Lens power | P = 1/f (diopters, D); convex +, concave - |
| Critical angle & TIR | sin(θc) = n₂/n₁; total internal reflection if θ > θc |
