Sample questions

Question 1

The radii of curvature of the two surfaces of a lens are 20 cm and 30 cm and the refractive index of the material of the lens is 1.5. If the lens is concave- convex, then the focal length of the lens is

Question 2

A convex lens of focal length f forms a real image of an object. If the object moves towards the lens from infinity, its image will move:

Question 3

An equiconvex lens has a focal length f. If the lens is cut into two identical plano-convex lenses, what is the focal length of each part?
