A thin converging lens of focal length f= 25 cm forms the image of an object on a screen placed at a distance of 75 cm from the lens. The screen is moved closer to the lens by a distance of 25 cm. The distance through which the object has to be shifted, so that its image on the screen in sharp again is

A thin converging lens of focal length f = 25 cm forms the image of an object on a screen placed at a distance of 75 cm from the lens. Now the screen in moved closer to the lens by a distance of 25 cm. The distance through which the object has to be shifted so that its image on the screen is sharp again is

A thin converging lens of focal length f=25.0 cm forms the image of an object,on the screen,at a distance 5m from the lens. The screen is then drawn closer by a distance of 18cm. By what distance should the object be shifted so that its image on the screen is sharp again?

A thin converging lens of focal length 25.0cmforms the image of an object, on the screen, at a distance 5m from the lens. The screen is then drawn closer by a distance of 18cm. By what distance should the object be shifted so that its image on the screen is sharp again?

A thin converging lens with focal length f = 25 cm projects the image of an object on a screen removed from the lens by a distance l == 5.0 m . Then the screen was draws closer to the lens by a distance Delta l = 18 cm . By what distance should the object be shifted for its image to become sharp again ?

A lens with a focal length of 25 cm produces real image of an object at a distance of 50 cm from the lens. At what distance the object placed from the lens?

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.
