The graph shown relationship between object distance and image distance for a equiconvex lens. Then focal length of the lens is `

The graph between object distance u and image distance v for a lens is given below. The focal length of the lens is. .

The graph between objecct distance u and image distance v for lens is givenn beow. The focal length of the lens is

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.

If in a convex lens object and its image distances are each equal to d, the focal length of the lens is

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.

The graph in shows the variation of image distance (v) with object distance (u) in case of a lens. Find focal length of the lens. What is the nature of the lens, if image formed is real ? .

Draw a ray diagram to show the formation of the image of an object placed between the optical centre and focus of a convex lens. Deduce the relationship between object distance, image disatnce and focal length of lens.
