Real image and Virtual image

Plane Mirror and its characteristics|Law of propagation of light|Real and Virtual object|Law of reflection|Locating images formed by two mirrors

Mark the correct option A) If the incident rays are converging,we have a real object B) If the final rays converging.we have a real image C) The image of a virtual object is called a virtual image D) If the image is virtual,the corresponding object is called a virtual object

In astronomical telescope final image is (1) Real erect (2) Real inverted (3) Virtual errect (4) Virtual inverted

When an object is at a distance u_(1) and u_(2) from the optical centre of a lens, a real and virtual image are formed respectively, with the same magnification.The focal length of lens is:

When the object is at distance mu_1 and mu_2 from the optical centre of a convex lens, a real and a virtual image of the same magnification are obtained. The focal length of the lens is

When an object is at a distance 3 meters and 1meters from the optical centre of a convex lens, a real and virtual image are formed respectively, with the same magnification. Find the focal length of the lens (in meters)

Given an optical axis MN and the positons of a real object AB and its image A 'B' , detormine diagramatically the positon of the lens (its optical centre O ) and its foci, it it a converging or diverging lens? Is the image real or virtual?
