## Is parabolic mirror used in headlights?

Detailed Solution. The correct answer is Parabolic Concave mirror. A parabolic concave mirror is used in the headlamps of the car as a reflector. These mirrors are capable of directing the light at a particular point as they have converging power.

## Why are parabolic mirrors used for car headlights?

Concave mirror has converging power, it can concentrate the light ray at a particular point. And in night we want highly concentrated light beam for clear visibility. This is why concave mirror is used.

In terms of a car headlight, this property is used to reflect the light rays emanating from the focus of the parabola (where the actual light bulb is located) in parallel rays. This property is used in a converse fashion when one considers parabolic antennae.

Why the car headlights are concave and parabolic in shape?

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 concave mirror is a converging mirror as opposed to a convex mirror which is a diverging mirror.

### Which type of mirror is used in headlight?

Concave mirrors
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.

### Which type of mirror is used in car headlight Why?

Detailed Solution The Correct Answer is concave mirror. A concave mirror is used in a car headlight. The explanation is that a concave mirror is a converging mirror, as opposed to a convex mirror, which is a diverging mirror. The bulb is held at the middle of the mirror in the headlights.

Why do we use parabolic mirror instead of concave mirror?

The thing is that the usual made concave mirror has spherical surface whereas the parabolic mirror has parabolic surface in which the spherical aberration is less. To minimize the spherical aberration, parobolic mirrors can be used mainly in astronomical telescopes to enhance image quality.

Which mirror is used in car headlights and why?

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.

## Why a car headlight with a parabolic reflector is better than one with an unreflected light bulb?

A parabolic reflector reflects most of the light rays from the light bulb and only a small amount of direct rays disperses as stray light (Fig. 29.4B). The intensity of reflected light is strongest near the beam axis (except for light cut off by the bulb itself), and drops towards the outer edge of the beam.
