Question

Find two values of object distance, for which a convex lens of power 2.5D will produce an image that is four times as large as the object.​

Answer 1

Answer:

Here f is the magnitude of the focal length of the lens. Hence. find the two values of object distance for which a convex lens of power 2.5 D will produce an image that is four times as large as the object. |u| = 50 cm or 30 cm
