Why do you think a converging (convex) lens is used to correct a visual effect called farsightedness and not a diverging lens? 25. WebConcave mirrors are used to concentrate the sunlight onto the pipe. The mirror has the approximate shape of a section of a cylinder. For the problem, assume that the mirror is exactly one-quarter of a full cylinder.

WebConverging lenses, like those normally found in reading glasses, have positive refracting powers. Diverging lenses, like those worn by people with myopia or near-sightedness, have negative refracting powers. A flat piece of glass, which is essentially the same as no lens at all, has a power of zero. The eye has a power of 50 D when focusing on ... WebA convex lens is also known as the converging lens as the light rays bend inwards and converge at a point which is known as focal length. On the other hand, the concave lens is also known as a diverging lens because it bends the parallel light rays outward and diverges them at the focal point.

For converging lenses, the focal length is always positive, while diverging lenses always have negative focal lengths. However, these conventions are arbitrary, and physicists could just as easily have made the signs opposite.
