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. WebThus, the focal length of the lens is the distance from the lens to the spot, and its power, in diopters (D), is the inverse of this distance (in reciprocal meters). Solution The focal … WebAn object is placed to the left of two converging lenses, as shown in (Figure 1). Lens 1 has a focal length f and lens 2 has a focal length 2f.
