Designed with EdrawMax, this template illustrates the concept of the power of a lens. It features two lenses, Lens - 1 in pink and Lens - 2 in orange. Parallel light rays enter each lens. Lens - 1 has a shorter focal length because it bends or converges the light rays more, as indicated by the closer focal point (F). In contrast, Lens - 2 has a longer focal length since it causes less bending or convergence of the light rays. This visual aid is useful for understanding the fundamental principle in optics that the power of a lens is inversely related to its focal length. It can serve as an educational tool in physics to teach students about lens properties.
