Uses Of Convex Mirror
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. The term ‘diverging mirror’ is based on its behaviour of making rays diverge upon reflection. This means that when a parallel light ray hits a convex mirror, it reflects outwards and travel directly away from an imaginary focal point.
Some convex mirror uses are listed in the points below.
Inside buildings
Vehicle mirrors
Magnifying glass
Security purposes
The convex mirror always forms a virtual image of the object and the image formed by the convex mirror is smaller than the size of the actual object. Therefore, the most common convex mirror uses are in places where bigger objects are to be viewed in a smaller size. Since convex mirrors have a wider view field than concave mirrors and plane mirrors, they are mostly used inside mirrors of automobiles. Some of the most vital and common uses of convex mirror is described below.
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.
These were some of the common convex mirrors uses in the practical world. Convex mirrors are also used in various other places like as a street light reflectors as it can spread light over bigger areas. They are also used to make telescope and ceiling dome mirrors.
Uses Of Concave Mirror

A concave mirror which is also called a converging mirror has its reflecting surface bulging inwards, i.e. away from the incident light. There are numerous uses of concave mirrors in daily life. It is used in the aircraft landing to guide the airplane, it is used as a torch to reflect the light rays, it is used during shaving to get an erect and enlarged image of the face, etc.
Some concave mirror uses are listed in the points below.
Shaving mirrors
Head mirrors
Ophthalmoscope
Astronomical telescopes
Headlights
Solar furnaces
Concave mirrors reflect light inward to one focal light. Therefore, they are mostly used to focus light. A concave mirror shows different image types depending on the distance between the mirror and the object. Concave mirrors are called converging mirrors because as light falls on the mirror, it collects the light and refocuses the parallel incoming rays. Some of the most important and common applications of the concave mirror are described below.
Used in shaving mirrors
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.
Used in solar furnaces
Large concave mirrors are used to focus sunlight to produce heat in the solar furnace. They are also used in solar ovens to collect a large amount of solar energy in the focus of the concave mirror for heating, cooking, melting metals, etc.
Answer:
concave Mirror: A concave mirror has the reflecting surface that caves inwards. Concave mirrors converge light to one prime focus point. Therefore, they are also called converging mirrors. They are used to focus light.
Convex Mirror is a curved mirror where the reflective surface bulges out towards the light source. This bulging out surface reflect light outwards and are not used to focus light.
