An object approaches a convergent lens from the left of the lens with a uniform speed 5 m/s and stops at the focus, the image

An object appraches a convergent lens from the left of the lens with a uniform speed 5m//s and stops at the focus. The image

When an object approaches a convex lens from infinity, the image formed by it shifts

An object is approaching a convex lens of focal length 0.3m with a speed of 0.01m s^(-1) . Find the magnitudes of the ratio of change of position and lateral magnification of image when the object is at a distance of 0.4m from the lens

A converging lens can from a virtual image if the object is placed

A lens forms a real image of an object. The distance from the object to the lens is x cm and that from the lens to the image is y cm. The graph shows the variation of y with x. It can be deduced that the lens is

An object is placed at the focus of concave lens having focal length /. What is the magnification and distance of the image from the optical centre of the lens ?

If an object is placed at the focus of a convex lens, where is the image formed?

An object is placed at the focus of a concave lens. Where will be image ?
