Question

The concave mirrors are used in

Answer 1

Concave mirror:

1. If a hollow sphere is cut into parts and the exterior surface of the cut part is painted, then it becomes a mirror with its internal surface as the reflecting surface.
2. This type of mirror is called as a concave mirror.
3. It has a reflective surface that is curved inward and away from the light source.
4. Concave mirrors reflect light inward to one focal point known as foci.
5. Unlike convex mirrors, the image formed by a concave mirror shows different images depending on the distance between the object and the mirror.

Uses of the concave mirror:

Concave mirrors reflect light inward to one focal light. Therefore, they are mostly used to focus light. Listed below are uses of concave mirrors

1. Shaving mirrors
2. Head mirrors
3. Ophthalmoscope
4. Astronomical telescopes
5. Headlights
6. Solar furnaces

Thus, the concave mirrors are used in reflecting telescopes as parabolic mirrors, in magic lanterns, in cinema projectors, etc.
