Work of a convex lens is:

Question

Question

Answer 1

CONCEPT:

Concave lens: It is a diverging lens that diverges the parallel beam of light.
- It can also gather light from all directions and project it as a parallel beam.
- The focal length of the concave lens is negative.
- It has a virtual focus from the diverging rays of light that seem to converge.
Convex lens: The lens whose refracting surface is upside is called a convex lens.
- The convex lens is also called a converging lens.
- The focal length of a convex lens is positive.

EXPLANATION:

From the above, it is clear that the convex lens works as a converging lens because it converges the light that incidents on it. Therefore option 1 is correct.
