What are the uses of concave and convex mirrors in our daily life?
A concave mirror, which is also called a converging mirror has its reflecting surface bulging inwards, i.e. away from the incident light.
Concave mirrors are most commonly used in shaving because of their reflective and curved surface. During shaving, the concave mirror forms an enlarged and erect image of the face when the mirror is held closer to the face.
Concave mirror uses in the ophthalmoscope
Concave mirrors are used in optical instruments such as Ophthalmoscope. Ophthalmoscope consists of a concave mirror with a hole in the center. The doctor focuses through the small hole from behind the concave mirror while a light beam is directed into the pupil of the patient’s eye. This makes the retina visible and makes it easy for doctors to check.
Uses of concave mirror in astronomical telescopes
Concave mirrors are also used in making astronomical telescopes. In an astronomical telescope, a concave mirror of a diameter of 5 meters or more is used as the objective.
Concave mirrors used in headlights
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.
A convex mirror is a spherical reflecting surface in which its bulging side faces the light source. There are numerous uses of convex mirror which is also referred to as a fish-eye mirror by automobile enthusiasts and diverging mirror by physicists.
Convex mirrors used inside buildings
Large offices, stores, and hospitals use a convex mirror to let people see around the corner so that they can avoid running into each other and prevent any collision.
Convex mirror used in vehicles
Convex mirrors are widely used as rear-view mirrors in automobiles and vehicles because it can diverge light beams and make virtual images.
Uses of the convex mirror in a magnifying glass
Convex mirrors are widely used for making magnifying glasses. In order to make a magnifying glass, two convex mirrors are placed back to back.
Convex mirrors used for security purposes
Convex mirrors are also used for security purposes in various places. They are places near ATM’s so that bank customers can check if someone is behind them.

What are the uses of concave and convex mirrors in our daily life?
Concave mirrors are used for various purpose:-1) A concave mirror is used as a reflector in torches, search lights, head lights of motor vehicles etc. to get powerful parallel beam of light. 2. A concave mirror is used as doctors head mirrors to focus light on the body parts like eyes, ears, nose, throat etc., to be examined. 3. A concave mirror is also used as a shaving mirror/makeup mirror, as it can form erect and magnified image of the face. 4. The dentists use concave mirror to observe large images of the teeth of the patient. 5. Large concave mirrors are used to concentrate sunlight to produce heat in solar cookers, solar furnace etc. 6. Large concave mirrors are also used in reflecting type telescope.Convex mirrors are used for various purposes:- 1. A convex mirror is used as a reflector in street lamps. As a result, light from the lamp diverges over a large area. 2. A convex mirror is used by drivers of automobile as a real view mirror. These mirrors are fitted on the sides of the vehicles enabling the driver to see traffic behind for safe driving. This is because (i) A convex mirror produced an erect image of the object. (ii) Size of image formed by convex mirror is much smaller than the object. (iii) Convex mirrors have a wider field of view as they are curved outwards. Therefore, convex mirrors enable the driver to view much larger area than would be possible with a plane mirror.
What are the uses of concave and convex mirrors in our daily life?
Concave mirror
1.concave mirror is used by dentist to see enlarged image of patient teeth
2.cancave mirror is also used for makeup and shaving to see enlarged view of the face
3.concave mirror is used for telescope
Convex mirror
1.convex mirror is also used for side mirror of cars bcoz they increase of field view
2.convex mirror is used for street lamps bcoz they spread the light over the ground
3.convex mirror is also used for security purpos in cctv cameras bcoz we can see image over the ground
