NettetThese equations, called the thin-lens equation and the lens maker’s equation, allow us to quantitatively analyze thin lenses. Consider the thick bi-convex lens shown in Figure 2.24. The index of refraction of the surrounding medium is n 1 (if the lens is in air, then n 1 = 1.00) and that of the lens is n 2.
