WebCorrect option is A) Converging lens directs light to a point at the optical center or axis of the lens. A lens that converts parallel rays of light to convergent rays and produces a real image. As long as the object is outside of the focal point the image is real and inverted. WebA lens is a transmissive optical device that focuses or disperses a light beam by means of refraction.A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (elements), usually arranged along a common axis.Lenses are made from materials such as glass or plastic and are ground, …
