Question 2
(a) State difference between a convex and a concave lens in their
(1) appearance,
(ii) action on the incident light, and
(iii) focus.
​

Answer 1

Answer:

Concave and Convex are two types of lenses that possess variation in physical shape as well as their properties. The crucial difference between concave and convex lens is that a concave lens diverges the light rays that incident on its surface. On the contrary, a convex lens has the ability to converge the light rays passing through it.These two lenses display distinct properties and have different applications according to the shape of the lense.
