C)combination of converging-diverging lens.

Question

Quizplus · Accepted Answer

A converging lens or convex lens is thicker in the middle and thinner at the edges. When parallel light rays pass through a converging lens, they bend towards each other and meet at a focal point, where the image is formed. This property of converging lenses makes them useful in magnifying and focusing applications, such as in telescopes, binoculars, and cameras. Diverging lenses or concave lenses, on the other hand, bend light rays away from each other and are used to correct near-sightedness or myopia. A combination of converging and diverging lenses can be used to correct astigmatism, a condition where the eye has different refractive powers in different meridians.
