Question

write short notes on concave and convex lens​

Answer 1

Explanation:

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. ... When these lenses are combined they produce sharper images.

Answer 2

Explanation:

concave lens is diverging lens. there r 3 types of concave lens- Plano concave, concavo convex, bi concave lens.

convex lens is converging lens. there r 3 types of convex lens- Plano convex, convexo concave and bi convex lens.
