If we use a concave mirror for our car, we will not be able to see the vehicles behind us properly. This is because the concave mirror will magnify the object and we will see a very enlarged image. This is because a convex mirror forms a highly-diminished image, thus making the traffic look much smaller.
Then, why concave mirror is used in vehicles?
Convex mirrors are commonly used as rear-view (wing) mirrors in vehicles because they give an erect, virtual, full size diminished image of distant objects with a wider field of view. Thus, convex mirrors enable the driver to view much larger area than would be possible with a plane mirror.
Additionally, what are the uses of concave mirror? Uses of concave mirrors:
- Concave mirrors are commonly used in torches, searchlights and headlights of vehicles to get powerful parallel beams of light.
- They are used as shaving mirrors to see a larger image of the face.
- Dentists use concave mirrors to view large images of the teeth of the patients.
Likewise, which mirror is used in vehicles?
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. They are used whenever a mirror with a large field of view is needed. For example, the passenger-side rear view mirror on a car is convex.
Why do we prefer concave mirror for real view in automobiles?
Convex mirrors are used in car rear view mirrors as they form a smaller image of the object. Concave mirror on the other hand forms magnified and inverted image of the object. This would form an image of a smaller area and would also inverted which would be hard to understand.

Which mirror is used in camera?
Concave mirrors are used in the electron microscopes and magnifying glasses , They are used in the visual bomb detectors and they are used in the flash light mirror of camera .
Which mirror is used in car headlights?
A concave mirror is used in the headlights of a car. a simple explanation for this would be: when a lighted bulb is placed at the focus of a concave mirror reflector, the diverging light rays of the bulb are collected by the concave reflection and then reflected to produce a string, parallel beam of light.
Which mirror is used in ambulance?
convex mirror
Which mirror is used in shaving mirror?
The concave mirrors are used as shaving mirrors because when the face is held within the focus of concave mirror then an enlarged image of the face is seen in the concave mirror.
Which mirror gives maximum wide view?
The convex mirror produces an upright image of any object and offers a wide viewing area as compared to the plane mirror.
Which mirror is used in solar furnace?
Concave mirrors are used in solar furnaces, because concave mirrors are the only type of mirror that reflects light in toward a single focal point. A flat mirror does not have a focal point. It does regular reflection off all of its points.
What is an example of a concave mirror?
Shaving and Makeup Mirrors Concave mirrors are often used as shaving mirrors and makeup mirrors. Objects held close are reflected in a concave mirror as a magnified image. When the mirror is held close to the face, an enlarged image of the skin can be seen.
What is the mirror in a car called?
A side-view mirror (often called side mirror), also known as the wing mirror , is a mirror found on the exterior of motor vehicles for the purposes of helping the driver see areas behind and to the sides of the vehicle, outside the driver’s peripheral vision(in the ‘blind spot’)
What type of mirror is used in torches?
A concave mirror is used in torch lights. The light rays from a source placed on the focus of a concave mirror are reflected in such a way that the reflected rays are strong, straight and parallel.
Which mirror is used in telescope?
Reflecting telescopes use mirrors instead of lenses to focus the light. A convex mirror is used to gather light and reflect it back to a focal point. In order to get the light out of the telescope, another mirror is used to direct the light to an eyepiece.
How do doctors use concave mirrors?
Why do doctors use concave mirrors for examining body parts? If the object is placed between the focus and pole of a concave mirror, it provides a virtual enlarged and erect image. So, the doctors use it as a magnifying tool. The concave mirrors provide a magnified reflection of whatever is being reflected.
What are the five uses of concave mirror?
Uses Of Concave Mirror Shaving mirrors. Head mirrors. Ophthalmoscope. Astronomical telescopes. Headlights. Solar furnaces.
Why ENT doctors use concave mirrors?
This is the reason why ENT specialists use it as a head mirror. The concave mirror is used as a shaving mirror because when an object is held between the pole and principal focus of a concave mirror, it forms a virtual, erect and magnified image of an object.
How does a concave mirror form an image?
A plane mirror will always produce a virtual image. A concave mirror will only produce a virtual image if the object is located in front of the focal point. A plane mirror will always produce an upright image. A concave mirror will only produce an upright image if the object is located in front of the focal point.
Which lens is called converging lens?
A convex lens is also called a converging lens because it makes parallel light rays passing through it bend inward and meet (converge) at a spot just beyond the lens known as the focal point. Photo: A convex lens makes parallel light rays converge (come together) at the focal point or focus.
What 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 used in compound microscope?
Normally, concave mirror is used in microscopes. In case of oil immersion, plane mirrors can be used. In general, compound microscope contains a system of lenses that work together to increase the size of the image.
What is meant by concave mirror?
A concave mirror, or converging mirror, has a reflecting surface that is recessed inward (away from the incident light). Concave mirrors reflect light inward to one focal point. They are used to focus light.
