CBSE Class 12-science Answered
The radii of curvature of the faces of a double convex
lens are 10 cm and 15 cm. If focal length of the lens is 12 cm, find the
refractive index of the material of the lens.

Expert Answer
Using the lens makers formula:
here for convex lens, R1 = 10 cm, R2 = -15 cm
Solving the above equation we get
Refractive index of the material of the lens, n = 1.5
