Thin Lens Formula
XII
⚡ Quick Summary
Relates focal length, object distance, and image distance for a thin lens.
['1/f = (μ - 1)(1/R₁ - 1/R₂)', '1/v - 1/u = 1/f']
The focal length of a thin lens is related to the radii of curvature of its surfaces and the refractive index of the lens material by the Lens Maker's Formula. The thin lens equation relates the object distance (u), image distance (v), and focal length (f) of a lens: 1/v - 1/u = 1/f
