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 mirror is used in cars and why?
The side mirrors of the car and the rear view mirror of a car are made up of convex mirrors. This is because the image formed by a convex mirror is diminished and erect image, thus it provides a larger field of view.

Convex mirror: different uses
One of the most common uses for the convex mirror is the passenger-side mirror on your car. These convex mirrors are used for cars because they give an upright image and provide a wider field of view as they are curved outwards.
Why are car mirrors convex?
The images reflected in a convex mirror, then, look smaller than they are — they’re compressed. This is why convex mirrors are used on cars: They reflect more in a smaller space. In other words, a convex mirror has a wider field of view than a flat one, which can only reflect the area right in front of it.
Which mirror is used in headlight of car?
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.
Where are concave mirrors used?
Concave mirrors are widely used in headlights of automobiles and motor vehicles, torchlights, railway engines, etc. as reflectors. The light source is placed at the focus of the mirror, so after reflecting the light rays travel over a huge distance as parallel light beams of high intensity.
Is dentist mirror concave or convex?
A concave mirror gives the dentist a magnified reflection of the mouth while also refracting a bit of light. This means the image in the mirror is larger, brighter, and, for the dentist, easier to see.
Why do cars have rear view mirrors?
So, the convex mirrors enable the driver to view much larger area than a plane mirror. The images produced are erect and their size is much smaller than the object. Hence, it is used as a rear view mirror in automobiles to see objects at the backside of the vehicle.
What happens if concave mirror is used as rear view?
If a concave mirror is used as a rearview mirror of a vehicle as a concave mirror produces the completely inverted image of the real image to be produced. When we use a concave mirror the image of the distant object gets inverted so it is not physically possible to use them.
Why did cars only have one side mirror?
It cost extra and had to be installed by the dealership if a buyer wanted one. Still to this day, the law requires only a rear-view mirror and a driver’s-side mirror (though many states specify that a car must possess all the safety equipment that was originally installed at the factory to pass inspection).
Why concave mirror is used in headlight?
Concave mirror are used in car headlamp. 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.
Which mirror is used in flashlight?
Concave mirror is used as torch reflector.
Which mirror is used in telescope?
In a reflector, light enters the telescope at the end opposite the primary mirror. The mirror is a concave mirror. Similar to a convex lens, a concave mirror converges the light at the secondary mirror. The rays of light converge at the focal point.
