REFLECTION AT CURVED SURFACES & REFRACTION AT CURVED SURFACES:
1. Magnification : m = -v/u or m=hi/ho
2. Mirror formula, 1/f = 1/u + 1/v
3. focal length f = R/2
4. Lens formula 1/f = 1/v - 1/u
5. Lens makers fomula : 1/f = (n-1) (1/R1 - 1/R2)
6. The relation between refractive indices of media, object distance, image distance, and radius of curvature is given by :
