QUESTION #17 Lens Maker's Formula
A bi-convex lens has radius of curvature of both the surfaces same as 1/6 cm. If this lens is required to be replaced by another convex lens having different radii of curvatures on both sides ( R₁ ≠ R₂ ), without any change in lens power then possible combination of R₁ and R₂ is:
