To observe image formation by thin lenses and to compare results with those given by the simple lens equation.

e focal point of a converging lens is defined as that point where a beam of incoming parallel light rays will be brought to a focus. For a diverging lens, a beam of parallel light rays will be spread ... will appear to diverge from a focal point located in front of the lens. Since lenses can bend light rays as stated above, it is therefore possible to form images using lenses. The location and nature ...
