## Why concave lens is known as converging lens?

Because a convex lens concentrates the light rays that are incident on it, it is called a converging lens. … The ray through the optical center emerges un-deviated along its original direction. The distance from the optical center to the focal point is called the focal length of the lens.

## Which lens is called converging lens and why?

A convex lens is called as converging lens because it bends inward the light falling on it.

## What is concave lens also called?

A concave lens is also known as a diverging lens because it is shaped round inwards at the centre and bulges outwards through the edges, making the light diverge.

## What is the difference between concave and convex lens?

A convex lens is thicker at the centre and thinner at the edges. A concave lens is thicker at the edges and thinner at the centre. Due to the converging rays, it is called a converging lens.

## Which lens is known as diverging lens?

The concave lens is a diverging lens, because it causes the light rays to bend away (diverge) from its axis.

## What is the magnification produced by a concave lens?

The image formed by a concave lens is always smaller than the object, therefore, the magnification produced by a concave lens is always less than 1.

## What are the difference between converging and diverging lenses?

A converging lens is said to have positive focal length. A converging lens causes exiting rays to be more convergent coming out than they were entering the lens. A diverging lens is said to have negative focal length. … A ray along this axis passes through the lenses without any change of direction due to refraction.
