We use convex mirror as a rear view mirror in the vehicles because convex mirror always forms virtual, erect and diminished images irrespective of distance of the object. A convex mirror enables a driver to view large area of the traffic behind him.
How are convex mirror useful to car drivers?
A convex mirror is preferred as a rear-view mirror in cars and vehicles as it gives a wider field of view, that helps the driver to see most of the traffic behind him. Convex mirrors always form an erect, virtual, and diminished image of the objects placed in front of it.
Why are convex mirrors used as vehicular mirrors?
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.
Why are convex mirrors useful?
A convex mirror bends light as it reflects the light, and the farther away a point is from the center, the more the light is bent. … Because the image is smaller, more image can fit onto the mirror, so a convex mirror provides for a larger field of view than a plane mirror. This is why they are useful.
Is concave lens?
A concave lens is a lens that possesses at least one surface that curves inwards. … It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia).
Which mirror is convex in a car?
In the USA the passenger side mirror is a convex mirror but the driver’s side mirror is a flat/plane. Convex mirrors are used on the outside mirrors of cars because they provide a wide field of view and the image is upright.
Where do we use concave mirrors?
Concave mirrors are used as searchlights, shaving mirrors, satellite dishes, and many more. These mirrors have the property to collimate and concentrate light rays. Concave mirrors in torches and headlights are used as reflectors.
Is a mirror a convex?
A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source. Convex mirrors reflect light outwards, therefore they are not used to focus light. … The image is smaller than the object, but gets larger as the object approaches the mirror.
What type of image do convex mirrors create?
The image produced by a convex mirror is always virtual, and located behind the mirror. When the object is far away from the mirror the image is upright and located at the focal point.

What is convex lens and how is it used in daily life?
Uses of convex lens are in daily life are as follows : 1) Convex lens is used in microscopes and magnifying glasses to subject all the light to a specific point. 2) Convex lens is used as a camera lens in cameras as they focus light for a clean picture. 3) Convex lens is used in the correction of hypermetropia.

What are the application of concave lens?
Concave lenses are used in telescope and binoculars to magnify objects. As a convex lens creates blurs and distortion, telescope and binocular manufacturers install concave lenses before or in the eyepiece so that a person can focus more clearly.
