Light – Reflection & Refraction — Key Formulas
| Formula | Expression |
|---|---|
| Mirror formula | 1/v + 1/u = 1/f (v = image distance, u = object distance, f = focal length) |
| Magnification (mirror) | m = −v/u = height of image / height of object |
| Lens formula | 1/v − 1/u = 1/f |
| Magnification (lens) | m = v/u = height of image / height of object |
| Power of a lens | P = 1/f (f in metres) · Unit: dioptre (D) · Convex = +, Concave = − |
| Refractive index | n = speed of light in vacuum / speed in medium = sin i / sin r |
