At which position will you keep an object in front of a convex lens so as to get a real image of the same size as the object? Draw a figure.

Text Solution

Verified by Experts

To get a real image of the same size as the object, the object should be placed at a distance equal to twice the focal length of the lens i.e., at a point `2F_(1)` from the lens as shown in the ray diagram.
