Answer 2

Answer: Concave mirrors are used in the following used cases . They are

               as follows :-    

Shaving mirrors

Ophthalmoscope

Astronomical telescopes

Headlights

Solar furnaces

Explanation:

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.

These were some common uses of the concave mirror in daily life. Concave mirrors are also used in satellite dishes, electronic microscope, visual bomb detectors, etc.
