These mirrors in the vehicles help in cutting down the blind spots as long as the object is in their focus. A concave mirror, on the other hand, has the reflecting surface, which bends inwards and is away from the light source.
Why concave mirror is used in cars?
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 vehicles and why?
Convex mirrors are used as rear-view mirrors in motor vehicles because they form virtual, erect and diminished images irrespective of distances of the object. Convex mirror helps the driver to view large areas of the traffic behind him and he can easily detect the vehicle coming or running behind him.
Why are convex mirrors used as side mirrors in vehicles?
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 convex mirrors are used in vehicles for rear view?
We prefer a convex mirror as a rear-view mirror in vehicles because it gives a wider field of view, which allows the driver to see most of the traffic behind him. … Convex mirrors always form a virtual, erect, and diminished image of the objects placed in front of it.
What are 3 types of mirrors?
Three common types of mirror are the plane mirror, which has a flat, or plane, surface; the convex mirror; and the concave mirror.
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).
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.
Which mirror is used in solar cooker?
Note: A plane mirror can be used in a solar cooker but it cannot concentrate the rays at point as the concave mirror does. Thus, the maximum heat will not be achieved. A convex cannot be at all since it will diverge away the sun rays falling on it.
Where is concave mirror used?
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.
Why are convex mirrors used in street lights?
Convex mirrors are used as reflectors in street lights because they are able to spread the light over a wide area.
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.
Which mirror is used by dentist?
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.
Which type of image is formed in concave mirror?
Image formed by a convex mirror is always virtual and erect. When an object is placed at infinity, virtual image is formed at focus and the size of the image is smaller.

What is the other name of convex mirror?
Convex mirror is also known as a diverging mirror as this mirror diverges light when they strike on its reflecting surface. Virtual, erect and diminished images are always formed with convex mirrors, irrespective of the distance between the object and the mirror.
Why we use a plane mirror to see your face?
Plane mirror causes regular reflection of light. When a parallel beam of light is incident on a plane mirror it is reflected back parallely. Due to this property a plane mirror is used to see our image and not a rough surface.
