Uses of Concave Mirror

Uses of Concave Mirror: A curved mirror is one that has a curved reflecting surface and is either bulged outward or recessed inward. The ones bulging outward are convex mirrors and recessed inward are concave mirrors. The surfaces of most curved mirrors are formed like a section of a sphere, however different shapes are occasionally utilised in optical equipment. Parabolic reflectors, which are used in optical equipment that require to picture of distant objects, are the most frequent non-spherical kind. Mirrors that distort the image are used for fun. They have convex and concave sections that cause images to be intentionally distorted. When the object is put at particular distances, they also offer extremely magnified or highly decreased images.

What are the uses of the concave mirror in Hindi?

एक घुमावदार दर्पण वह होता है जिसमें एक घुमावदार परावर्तक सतह होती है और यह या तो बाहर की ओर उभरी हुई होती है या अंदर की ओर झुकी होती है। जो बाहर की ओर उभरे होते हैं वे उत्तल दर्पण होते हैं और अंदर की ओर अवतल दर्पण होते हैं। अधिकांश घुमावदार दर्पणों की सतहें एक गोले के एक भाग की तरह बनती हैं, हालांकि कभी-कभी ऑप्टिकल उपकरणों में विभिन्न आकृतियों का उपयोग किया जाता है। परवलयिक परावर्तक, जो ऑप्टिकल उपकरणों में उपयोग किए जाते हैं जिन्हें दूर की वस्तुओं की तस्वीर की आवश्यकता होती है, सबसे अधिक गैर-गोलाकार प्रकार होते हैं। छवि को विकृत करने वाले दर्पणों का उपयोग मनोरंजन के लिए किया जाता है। उनके पास उत्तल और अवतल खंड हैं जो छवियों को जानबूझकर विकृत करने का कारण बनते हैं। जब वस्तु को विशेष दूरी पर रखा जाता है, तो वे अत्यधिक आवर्धित या अत्यधिक घटे हुए चित्र भी प्रस्तुत करते हैं।

Uses of Concave Mirror and Convex Mirror

Concave Mirror

Light is reflected inward by concave mirrors, resulting in a single focal point. As a result, they’re usually utilised to concentrate light. Depending on the distance between the mirror and the object, a concave mirror will produce different image types. Concave mirrors are known as converging mirrors because they catch the light as it falls on them and redirects the parallel incoming rays. The following are some of the most important and common applications of the concave mirror:

Shaving mirrors

Shaving is done most often with concave mirrors. This is due to their curved and shiny surface. The concave mirror creates an enlarged and erect image of the face when shaving. Shaving becomes safer when the mirror is held closer to the face.

Microscopes

A concave mirror is employed in the base of a microscope. After passing through the mirror, light from an external source is shone on the specimen. The concave mirror solely focuses light on the specimen in order to keep the surroundings dark. The mirror’s orientation can be altered by spinning it. An eyepiece is used to see the specimen.

Ophthalmoscope

Optical equipment such as the ophthalmoscope uses concave mirrors. A concave mirror with a hole in the centre is used as an ophthalmoscope. While a light beam is delivered into the pupil of the patient’s eye, the doctor focuses via the small hole from behind the concave mirror. This makes the retina visible and easier to examine by doctors.

Astronomical telescopes

Astronomical telescopes also make use of concave mirrors.

Headlights

Concave mirrors are commonly employed as reflectors in automotive and motor vehicle headlights, torchlights, and other applications. The light source is positioned at the mirror’s focal point. Furthermore, after reflecting, the light rays travel a long distance as parallel high-intensity light beams.

Solar furnaces

The solar furnace uses large concave mirrors to focus sunlight and generate heat. They’re also used in solar ovens to collect a lot of solar energy in the concave mirror’s focus for heating, cooking, melting metals, and other things.

Other Uses

Satellite dishes, electronic microscopes, visual bomb detectors, and other devices use concave mirrors.

Convex Mirror

A virtual, reduced, and the upright image is always visible in a convex mirror. The image grows larger as the thing moves closer to the mirror. The image shrinks in size and gets closer to the focus as the object moves away until it is reduced to a point in the focus when the object is at an infinite distance. They encompass a larger range of view than a regular plane mirror because everything seems smaller in the mirror.
Convex mirrors are excellent for glancing behind a driver’s automobile on the road, keeping an eye on a larger area for surveillance, and so on.
