Answer:
Explanation:
A lens is a transparent device with two curved surfaces, usually made of glass or plastic, that uses refraction to form an image of an object. Mirrors, which have curved surfaces designed to reflect rays, also form images. A system of lenses and/or mirrors forms an image by gathering rays from an object and then causes them to converge or diverge. The position to which the rays converge to or diverge from is the image. A real image is formed when the optical system causes the rays to converge to a point, a virtual image is formed at the location from which they seem to originate.
