Here for the solution, step one.
00:03
From equation 5, which is given in the question, the thin lens equation for refraction at a spherical surface is given by the following equation, which also known as version formula, that is n2 by v minus n1 by u is equal to n2 minus n1 by r.
00:24
Here, n1 is the refractive index of medium on both ends of the surface.
00:32
N2 is the reflective index of the surface.
00:36
R is the radius of the curvature.
00:40
V is the image distance and u is the object distance.
00:46
Now for the step 2, we draw the following figure to understand the problem.
