Identify the nature of the image formed by the eye lens of a human eye. Thus, the focal length of the plane mirror will also be infinite. (v)Image formed is a laterally inverted image i.e., right hand side of the object seems to be the left hand side and vice-versa. The image forms at infinity when the rays go parallel after interacting.Real Image: A real image is formed by the actual intersection of light rays after interacting with an optical medium. In World War II and earlier submarines it was the only means of gathering target data to accurately fire a torpedo, since sonar was not yet sufficiently advanced for this purpose (ranging with sonar required emission of an electronic "ping" that gave away the location of the submarine) and most torpedoes were unguided.
