Illustration demonstrating how changes in curvature affect the focusing of light in a biconvex lens. At top left, the curvature of the lens is low, the focal length is long and the focal point is more elongated. As the curvature of the lens increases, the focal length decreases. At bottom right, the curvature of the lens is high, and the light is focused to a small point, like in a camera, microscope or the human eye. | |
