A teacher gives a convex lens and a concave mirror of focal length of about 20 cm each to his student and asks him to find their focal lengths by obtaining the image of a distant object.The student uses a distant tree as the object and obtains its sharp image, one by one, on a screen. The distances d_(1) and d_(2) between the lens/mirror and the screen in the two cases and the nature of their respective sharp images are likely to be :

A converging beam of light forms a sharp image on a screen. A lens is placed in the path of the beam at 10 cm from the screen. It is found that the screen has to be moved 8 cm further away from the lens to obtain a sharp image. Find the focal length and nature of the lens.

An object is placed 30cm away from a convex lens of focal length 10cm and a sharp image is formed on a screen. Now, a convex lens is placed In contact with the convex lens. The screen now has to be moved by 45cm to get a sharp image again. The magnitude of focal length of the convex lends in (in cm)

In order to determine the focal length of a concave mirror, a student obtained the sharp image of a distant tree on a screen. In order to obtain a sharp image of a window grill of the laboratory on the same screen, in which direction should the screen be moved ?

An object and a screen are mounted on an optical bench and a converging lens is placed between them so that a sharp image is obtained on the screen. The linear magnification of the image is 25. The lens is now moved 30 cm towards the screen and a sharp image is ■ again formed on the screen. Find the focal length of the lens
