Question

Lens is a transparent medium bounded by two surfaces of which, one or both surfaces are spherical. The commonly used spherical surfaces may be convex or concave surfaces and medium generally used is glass. The effective diameter of the circular outline of a spherical lens is called aperture. Intensity of image formed by a lens-which depends on the amount of light passing through the lens, will vary as square of the aperture of the lens. Minimum distance between an object and its real image formed by a convex lens of focal length f is 4f. The focal length of a lens depends upon the radii of curvature of its surfaces and refractive index of the material the lens is made from. Q1. What is the radius of curvature of a convex lens if it produces a real image of same size at a distance 32 cm from it?​
