Focal length and refractive index relation
WebMar 5, 2024 · The focal length of a diverging lens is negative. 2. The power of a refracting interface, of radius of curvature r, separating media of refractive indices n 1 and n 2, is (2.5.3) P = n 2 − n 1 r. Sign convention: The radius of curvature of a convex surface or interface is positive; WebThe focal length, f, of a lens is given by 1/f = (n-1) (1/R1 - 1/R2) where n is refractive index of the material of the lens, R1 is radius of curvature of the surface of lens nearer to the …
