Explanation:
Hint : The lens maker's formula states that the focal length of a lens depends upon the refractive index of the material of the lens and the radii of curvatures of the two surfaces. It is used by lens manufacturers to make the lenses of particular power from the glass of a given refractive index. 1f=(n−1)(1R1−1R2) .
