Question

what are the uses is concave and convex lens​

Answer 1

Convex :

Convex lenses have a significant drawback when used in optical applications like binoculars and telescopes. Light is often passed through a convex lens incorrectly, causing the image to appear with incorrect colors. Concave lenses are used in binoculars and telescopes so what you see is the correct color.

Concave:

Uses of convex lens are in daily life are as follows : 1) Convex lens is used in microscopes and magnifying glasses to subject all the light to a specific point. 2) Convex lens is used as a camera lens in cameras as they focus light for a clean picture. 3) Convex lens is used in the correction of hypermetropia.

Answer 2

uses of convex lens = microscope,magnifying glasses, camera lens,correction of hypermetropia

uses of concave lens = Telescopes, Binoculars
