Linear Magnification in case of refraction through single surface is
What is the formula for linear magnification for lens?
v = Image distance
u = Object distance
why is magnification in terms of mirrors -v/u whereas in lenses it is v/u ?
Consider a curved surface between two different media with refractive indices n1 = 1 and n2 = 2. The relation between radius of curvature, image distance and object distance is given by
