WebApr 10, 2024 · 1 dioptre: 1 dioptre is the power of a lens whose focal length is 1 meter. 1D = 1m –1; The power of a convex lens is positive and that of a concave lens is negative. Meaning of “The power of a lens is +2.0 D” The lens is convex. The focal length of the lens is + 0.50 m. Meaning of “The power of a lens is -2.5 D” The lens is concave. WebThe principal focal length of a converging lens may be determined by forming an image of a very distant object on a screen and measuring the distance from the lens to the screen. This distance will be the focal length, since rays …
