Real Image

Consider the following statements regarding the real images formed with a converging lens. । -Real images can be seen only if the image is projected onto the screen .(2)The real image can be seen only from the same side of the lens as that on which the object is positioned. (3)Real images produced by converging lenses are not only laterally but also longitudinally inverted as with mirrors. Which of the above statement/statements is/are incorrect?

A thin converging lens forms the real image of certain real object magnified m times.The magnification of real image become n when lens is moved nearer to object by distance x . find focal length of the lens

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

Statement-1: When the upper half of a converging lens is missing, a real image formed by the lens for a real object will lack its lower half. Statement-2: The real image formed by a thin lens for a real object will be always inverted.

State the difference between real and virtual images. What type of image (real or virtual) is formed in the still water of a lake ?
