An object is placed at a distance of `f//2` from a convex lens. The image will be

A point object is placed at a distance of 15 cm from a convex lens. The image is formed on the other side of lens at a distance 30 cm from lens. When a concave lens is placed in contact with convex lens, image is shifted away further by 30 cm. calculate the focal lengths of the two lenses.

An object is placed at a distance of f/2 from a convex lens of focal length f. The image will be

An object is placed at a distance of f/2 from a convex lens of focal length f. The image will be

An object is placed at a distance of 15 cm from a convex lens.If the focal length of the lens is 60cm,find the image distance.

When an object is placed at a distance of 36 cm from a convex lens, an image of the same size as the object is formed. What will be the nature of image formed when the object is formed. What will be the nature of image formed when the object is placed at a distance of: a) 10 cm from the lens? b) 20 cm from the lens?

When an object is placed at a distance of 15 cm from a convex lens, a real image is formed at a distance of 30 cm. What is the focal length of the lens?

A 1 cm high object is placed at a distance of 2f from a convex lens. What is the height of the image formed?

An object is placed at a distance of 15 cm from a convex lens. If the focal length of the lens is 60 cm, find the image distance.
