Formation of real image using a biconvex lens is shown below : If the whole set up is immersed in water without disturbing the object and the screen positions, what will one observe on the screen ?

A convex lens forms a real image 16 mm long on a screen. If the lens is shifted to a new position without disturbing the object or the screen then again a real image of length 81 mm is formed. The length of the object must be

A convex lens makes a real image 4 cm long on a screen. When the lens is shifted to a new position without disturbing the object, we again get a real image on the screen which is 16 cm tall. The length of the object must be

It was observed that when the distance between an object and a lens decreases, the size of the image increases. What is the nature of this lens? If you keep on decreasing the distance between the object and the lens, will you still able to obtain the image on the screen? Explain

Sharp image of extended object which is placed perpendicular to the principle axis of a lens is eta times that of the object for a particular position of object on a screen. Without disturbing the position of object and screen, by shifting lens a position can be obtained where the sharp image is 1//eta times that of object. Ratio of difference between the two positions of lens to the focal length of lens is:

The magnification of the real images produced by a convex lens varies from one to infinity. What are the values of the distances of the object from the lens for these magnifications ?

Draw a ray diagram to show the formation of a real magnified image by a convex lens. (In your sketch the position of object and image with respect to the principal focus of lens should be shown (clearly).

A thin converging lens is placed between an object and a screen whose position are fixed. There are two positions of the lens at which the sharp image of the object is formed on the screen. Find the transverse dimension of the object if at one position of the lens the image dimension equal h' = 2.0 mm and at the other, h'' = 4.5 mm .

Real image of an object are formed on the fromed on the two positions of a lens separated by a distance 60cm If the distance between object and screen is 180cm then ,the focal length of the lens is:
