WebbOne is a convex lens with a thick central part swelled outward and curved, and the other is a concave lens with a thin central part dented inward and curved. The convex lens converges light rays traveling parallel with each other to a point using refraction of light passing through the lens.
Webb1 nov. 2024 · Diverging (concave) lenses. A diverging lens, as the name suggests, is a piece of specially shaped glass that has the effect of making light rays entering the lens on one side diverge or spread out from each other on the other side of the lens. They achieve this by being concave in shape. They curve inward in the middle (see figure 4). Webb13 juli 2024 · Concave lenses—those that are thicker around the edges than they are in the center— disperse light rays, which can have the effect of making things look smaller or …
