WebMar 3, 2024 · Convex and Concave Lenses are Spherical Lenses. We look at the Image Formation by these spherical lenses using ray diagrams. Light ray rules for Convex Lens ... Webmore. If you have myopia or nearsightedness, you would use diverging lenses (concave) to shift the focus of your eye lens backwards so that it can focus on the retina. Just the opposite goes for hypermetropia or farsightedness, in which you would use converging (convex) lens to bring the focus closer. night light on dual monitors

WebConvex (converging) lenses can form either real or virtual images (cases 1 and 2, respectively), whereas concave (diverging) lenses can form only virtual images (always … WebLenses can be concave or convex. A lens’s shape determines the images it forms. When parallel rays of light enter a concave lens, the light waves refract outward, or spread out. The light rays refract twice: first when entering the lens and second when leaving the lens. Only the light rays passing through the center of the lens remain straight. night light on a timer
