# Frequent question: Which kind of mirrors are used in the headlights of a motor car and why Class 10?

Contents

Concave mirror is used in headlights of vehicles, because when the bulb of headlight is placed at focus of concave mirror, it allows the light to spread out to infinity (longer distances).

## Which kind of mirrors are used in the headlights of a motor car and why?

A concave mirror or otherwise known as a converging mirror has a reflecting surface that is recessed inward. When an object is placed at its focus it produces its respective image at infinity (see figure). Thus they are used to focus light. Therefore, concave mirrors are in headlights of vehicles as reflectors.

## Which kind of mirrors are used in the headlights of a motor car and why ?( 1m?

Concave mirrors are used in head lights of vehicles because when the bulb of headlight is placed at focus of concave mirror it will allow the light to spread out to infinity after the reflection on the mirror.

## What is the mirror formula?

Suppose an object is placed u cm in front of a spherical mirror of focal length f such that the image is formed v cm from the mirror, then u, v and f are related by the equation; 1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.

## Are car headlights Convex mirrors?

Concave mirror is used in headlights of vehicles, because when the bulb of headlight is placed at focus of concave mirror, it allows the light to spread out to infinity (longer distances). … A convex mirror always diverges the rays of light falling onto it. Therefore, it is not used as headlights in cars.

## Which mirror is used in Periscope?

Only plane mirrors are used for a simple periscope. An expanded view of the object is required for some distance visions, and therefore convex mirrors are helpful. An erect image is produced by a double reversal of the object. Convex mirrors can be used to view objects that are too close to each other.
