A lens ( focal length 50 cm ) forms the image of a distant object which subtends an angle of 2 milliradian at the lens. What is the size of the image ?

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?

A convex lens of focal length 16 cm forms a real image double the size of the object. The distance of the object from the lens is

A convex lens of focal length 16 cm forms a real image double the size of the object. The image distance of the object from the lens is

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

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
