## Which of the two is called converging lens?

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

## What are the two types of converging lenses?

Convex (converging) lenses can form either real or virtual images (cases 1 and 2, respectively), whereas concave (diverging) lenses can form only virtual images (always case 3). Real images are always inverted, but they can be either larger or smaller than the object.

## Which one is a converging lens?

double convex lens
A double convex lens, or converging lens, focuses the diverging, or blurred, light rays from a distant object by refracting (bending) the rays twice.

## Which of the two is a converging lens convex or concave?

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. Due to the diverging rays, it is called a diverging lens.

## Which lens is converging and diverging?

Difference between concave and a convex lens
Concave LensConvex Lens
It is a diverging lens.It is a converging lens.
It is used as spy holes in doors, in optical instruments(telescope).It is used in compound microscope as eye piece, projectors and magnifying glass etc.

## Which lens is converging lens in air?

A lens behaves as a converging lens in air, so its refractive index is greater than 1: μ>1 , because the refractive index of air is equal to 1. A converging lens directs light to a spot near the lens’ optical centre or axis. A lens that provides a true image by converting parallel light beams to convergent light rays.

## Is a concave mirror converging or diverging?

We find that the rays reflect from the concave mirror, and according to the reflection laws the rays converge to a point on the principal axis. The image formed is a real image and this image is formed on the same side of the mirror. Hence, the concave mirror is a converging mirror.

## Which of the following lens is a diverging lens?

Concave lens
Concave lens is called a diverging lens. The working of the lens is dependent on the refraction of the light rays as they pass through the lens.

## Which of the following behaves as a converging mirror?

Note:Concave mirror acts as a converging mirror by focusing a parallel beam of light at a point known as the focus.

## When convex lens behaves as a converging lens can it be diverging explain?

A convex lens will act as converging when it is immersed in a liquid which has a lesser refractive index than the lens and act as diverging when the surrounding medium has a greater refractive index than it.

## What is focal length of a converging lens?

For a thin lens in air, the focal length is the distance from the center of the lens to the principal foci (or focal points) of the lens. For a converging lens (for example a convex lens), the focal length is positive and is the distance at which a beam of collimated light will be focused to a single spot.

## Which lens is known as converging mirror?

All the light rays reflected by concave mirror converges at its focus. Hence, concave mirror is also known as converging mirror.

## Is a convex lens always converging?

Yes , convex lens always converge light and it is because of the property of the convex lens. In this lens thickness is on the center and it converges all the light that are incident on it. So convex lens always converge light as it has the property of converging light.

## Why does a convex lens act as a converging lens and a concave lens as a diverging lens?

A convex lens converges the light rays of a parallel beam to a point after refraction through it. Hence a convex lens is also called a converging lens. A concave lens diverges the light rays of a parallel beam after refraction through it, Hence a concave lens is also called a diverging lens.

## Can a concave lens behave as a converging lens?

When concave lens is placed in a medium having refractive index ( ) greater the refractive index ( ) of the lens material, the concave lens behaves as a converging lens.
