Question

difference between Concave lens and convex lens​

Answer 1

Explanation:

A convex lens or converging lens focuses the light rays to a specific point whereas a concave lens or diverging lens diverges the light rays. A lens is a transparent material (either curved or flat surface) based on the principles of refraction. ... Most of the eyeglass lenses use combinations of convex and concave lenses.
