Question

Using the relation for refraction at a curved spherical surface, derive the expression for lens maker's formula.

Hint:

Lens Maker's Formula: \[ \frac{1}{f} = (n-1) \left( \frac{1}{R_1} -\frac{1}{R_2} \right) \] For a convex lens: \[ R_1>0, \qquad R_2<0. \] For a concave lens: \[ R_10. \]
