Formation of real image using a biconves 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 secreen ?

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 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

A convex lens forms a real image of the object when the lens is at a distance of 1 m from the object. The size of the image is 3 times that of the object. The position of the object and the screen are kept fixed but the distance of lens from the object is doubled. The image is now one half of the size of the object, the focal length of the lens is

A luminous object is lying in front of a screen at a distance d from it. What is the maximum focal length of a converging lens, which can be mounted between the object and the screen to cast the real image of the object on the screen ?

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:

Describe the formation of real and virtual images by a convex lens with the help of diagrams at different positions of the object.
