Concave mirror is used in projector lamps
Answers
Answer:
They also observed that the smaller the distance between the mirror and the object, the larger is the image formed. Hence, concave mirrors are used in projectors.

Answer:
Concave mirrors project a beam of light outward, which is what we want in a reflector or projector.
They used in things like TV or movie projectors to make light rays spread out into the distance and produce enlarged images.
Explanation:
A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex (bulging outward) or concave (recessed inward). Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices. The most common non-spherical type are parabolic reflectors, found in optical devices such as reflecting telescopes that need to image distant objects, since spherical mirror systems, like spherical lenses, suffer from spherical aberration. Distorting mirrors are used for entertainment. They have convex and concave regions that produce deliberately distorted images. They also provide highly magnified or highly diminished (smaller) images when the object is placed at certain distances.
