What is the difference between collecting and scattering lenses?
| August 30, 2020 | Education
If the relative refractive index of the convex lens material is greater than the relative refractive index of the environment, then the lens converts the parallel light beam into a converging one. Such convex lenses are called collecting lenses. In contrast to convex lenses, concave lenses under the same conditions convert a parallel beam of rays incident on them into a divergent one. Therefore, such concave lenses are called scattering.
