If the magnification of a body of size 2 cm is +3 for a convex lens then the size of image is………………… .

What is linear magnification? Write its expression for a convex lens.

Give the nature, position and size of the image formed by a convex lens when the object lies at 2 F

The size of the image of an object,which is at infinity, as formed by a convex lens of focal length 30 cm is 2 cm. If a concave lens of focal length 20 cm is placed between the convex lens and the image at a distance of 26 cm from the convex lens, calculate the new size of the image

An object of size 5 cm is placed at distance of 25 cm in front of a convex lens of focal length 20 cm. Find the size and nature of image and its distance from the lens.

An object is placed at a distance of f//2 from a convex lens .The image will be

Does size of mirror affect the nature of the image?

Does size of mirror affect the nature of images ?

Two lenses convex lens of focal length 30 cm in contact with a concave lens of focal length 20 cm, if they are placed 8.0 cm apart with their principal axes coincident. An object 1.5 cm in size is placed on the side of the convex lens. The distance between the object and the convex lens is 40 cm. Determine the magnification produced by the two-lens system, and the size of the image.
