Question

difference between concave and convex lens​

Answer 1

Answer:

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.

Answer 2

Answer:

convex lens :

An lens whose both side refracting surfaces are spherical such that it is thick in the middle and thin at the edges is known as convex lens.

concave lens:

A lens whose both refracting surfaces are spherical such that it is thin in the middle and thick at the edges is known as concave lens.
