Question

Find the radii of curvature of a convex-concave convergent lens
made of glass with refractive index n =1.5 having focal length of
24 cm. One of the radii of curvature is double the other.​

Answer 1

Explanation:

Focal lengthf=24cm. Where fis the focal length, nis the refractive index, R1,R2is the radii of curvature. Thus, the radii of curvature of a convexo-concave converging lens are 6cm and 12cm.
