Converging light rays are falling on a convex lens as shown in Fig.(a) If the focal length of the lens is 30 cm, then find the position of the image.

Converging light rays are falling on a convex lens. If the focal length of the lens is 30 cm, then find the position of the image.

Rays of light are falling on a convex lens of focal length 40 cm . As shown in Fig. Determine the position of the image. .

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 focal length of convex lens is 20 cm. If an object of height 4 cm is placed at a distance of 30 cm from the lens, find: The position of the image

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.

The focal length of a convex lens is 20 cm . If an object of height 4 cm is placed at 30 cm from the lens , find the position, nature and size of the image .

The focal length of a convex lens is 20 cm. If an object of height 2 cm is placed at 30 cm from the lens, find (i) the position and nature of the image (ii) the height of the image (iii) the magnification produced by the lens.

Graph of position of image vs position of point object from a convex lens is shown. Then, focal length of the lens is
