Why do flashlights use converging mirrors?

flashlights use concave mirrors. Convex mirrors are used because these mirrors provide a wider viewing angle than a plane mirror. This wide angle will help you getting more information/overview than what is happening at a narrow spot right behind the car if you use a plane mirror.

Why is a concave mirror used in torch?

Concave mirrors in torches and headlights are used as reflectors. The source of light is placed at the focus of a concave mirror such that the light rays emerge out as parallel beams, after getting reflected in the mirror.

What mirror is used in Torchlight?

Concave mirror
Concave mirror is used as torch reflector.

What will happen if there is no concave mirror in Torchlight?

Therefore, if there is no Concave mirror in torchlight then the vision will not be clear.

Why concave mirror is used in telescope?

Light enters the telescope at the right and travels to a concave mirror. The light is then reflected back again out of the back of the telescope to the eyepiece and the eye. Like the Reflector, uses a concave mirror as its primary objective to focus the incoming light.

Which mirror is known as converging mirror?

concave mirror
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. They are used to focus light.

What happens if concave mirror is used as rear view mirrors?

We cannot use a concave mirror as a rear-view mirror in vehicles because a concave mirror produces inverted images of distant objects. So, all the vehicles will be seen running upside down in the mirror.

Why concave mirror is converging but concave lens is diverging?

Light goes through, and is refracted by, a lens. Lenses have two focal points, one on either side of the lens. A concave mirror converges light to a focal point. A convex mirror diverges light, as does a concave lens.

What are the two uses of concave mirror?

Two uses of concave mirror are: (i) They are used as a reflector in the headlights of cars and in search of light. (ii) Doctors examine the throat, ear, nose and eyes with light focus with the help of a concave mirror.
