Suppose two transparent media having refractive indices µ1 and µ2 are separated by a spherical surface AB. Let C be the centre of curvature of AB. Consider a point object O in the medium 1. Suppose the line OC cuts the spherical surface at P. It is assumed that µ2 is greater than µ1 and the object O is on the convex side of the surface. Note: Although the formula is designed for a particular situation, it is valid for all situations of refraction at single spherical surface. This is because we have used the proper sign conventions.
