A converging lens is used to produce an image of an object on a screen. What change is needed for the image to be formed nearer to the lens?(a) increase the focal length of the lens (b) insert a perging lens between the lens and the screen(c) increase the distance of the object from the lens (d) move the object closer to the lens
(c) Increase the distance of the object from the lens
Explanation
In a converging lens, as the object moves away from the lens, the image gets closer to the lens.
For example: When the distance of the object is increased from the lens to infinity (considerable distance) in front of a convex lens, then the image is formed at $F$ on the right side of the lens (close to the lens).
While when the distance of the object is decreased from the lens to focus, $F'$ (closer to the lens) in front of a convex lens, then the image is formed at infinity on the right side of the lens (far from the lens).
