WebJan 25, 2024 · There are two types of lenses depending on converging or diverging light rays. The two types of lenses are: a. The convex lens (converging lens) b. The concave lens (diverging lens) Convex Lens A convex lens has spherical surfaces which bulge out in the middle. A convex lens is thicker in the middle and thinner at the edges.

WebThe diverging lenses are those that are thinner in its central part and thicker at the edges. As a consequence, they separate (diverge) the light rays that hit them parallel to the main axis. ...

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. open houses in pittsburghWebNov 5, 2024 · The simplest case is where lenses are placed in contact: if the lenses of focal lengths f1 and f2 are “thin”, the combined focal length f of the lenses is given by.
