Question

A student performed the experiment to find the position of images for the different positions of an object. If centre of curvature of convex lens is 20 cm, then match the following on the basis of above information:

Position of Image	Position of an object
(a) At infinity (b) beyond c (c) Image is 20 cm away from lens (d) Image is 10 cm from lens	(a)object is 20 cm away from lens  (b) At infinity (c) At 10 cm from lens (d) Between F and c

Answer 1

(a) → (c); (b) → (d); (c) → (a); (d) → (b)
