Answer
→If rays emanating from a point actually meet at another point after reflection and/or refraction, that point is called the image of the first point. →There are two types of image: (1) Real image : If the reflected rays actually converge at any point, then image is called the real image. (2) Virtual image: If the reflected rays do not actually meet but appear to diverge from the point when produced backward then image is called virtual image.
