An object is moving towards a converging lens on its axis. The image is also found to be moving towards the lens. Then, the object distance u must satisfy

If an object is moved towards a convex lens, the size of its image-

When an object moves towards a convex lens, the size of the image

When the object is moved slightly closer to a converging lens, the image may

When an object moves towards a convex lens, the size of the image decreases.

As an object moves towards a convex mirror, the image

An illuminated object is placed on the principal axis of a converging lens so the a real image is formed on the other side of the lens. If the object is shifted a little,

An illuminated object is placed on the principal axis of a converging lens so that real image is formed on the other side of the lens. If the object is shifted a little,
