# How virtual image is formed by concave mirror?

## How virtual image is formed by concave mirror?

The concave mirror forms a virtual image of an object, when the object is placed between the focus and pole of the mirror.

## What is virtual object in mirror?

Virtual object is an object that does not exist in real world. It is like a substitute for real object, or a make-believe of real object. An image in a mirror is a virtual object, which can in turn be used to create another image in a second mirror. All objects created in a series of mirrors are virtual objects.

What is virtual image of an object?

A virtual image (as opposed to a real image) is produced by an optical system (a combination of lenses and/or mirrors) when light rays from a source do not cross to form an image. As shown in the diagram below, the virtual image appears the same distance behind the plane mirror as the object is in front of the mirror.

Is the image real or virtual concave mirror?

Only a concave mirror can be used to produce a real image; and this only occurs if the object is located at a position of more than one focal length from the concave mirror. Plane mirrors never produce real images. A concave mirror will only produce a virtual image if the object is located in front of the focal point.

### What are the characteristics of a concave mirror?

A concave mirror diagram showing the focus, focal length, centre of curvature, principal axis, etc. A concave mirror, or converging mirror, has a reflecting surface that is recessed inward (away from the incident light). Concave mirrors reflect light inward to one focal point.

### What are the uses of concave mirrors?

Concave mirrors are used in motor vehicle headlights to send out strong beams of light. Instead of reflecting an image, they are used to focus the light from the bulb.

What are the properties of a convex mirror?

Thanks to the optical properties of convex mirrors, motorists have a buffer against all manner of dangers. Both side-view and rear-view mirrors are convex, which means that the image focal point is actually behind the mirrors and the reflected rays spread outward.

What are concave and convex mirrors?

Concave mirrors are also known as a converging mirror since the rays converge after falling on the concave mirror while the convex mirrors are known as diverging mirrors as the rays diverge after falling on the convex mirror. In this article, we will learn about image formation by concave and convex mirrors. Jul 22 2019
