Question

why are concave Mirrors used in Solar devices

Answer 1

Concave mirrors are used in solar furnaces, becauseconcave mirrors are the only type of mirror that reflects light in toward a single focal point. A flatmirror does not have a focal point. It does regular reflection off all of its points. ... The light will reflect up and away from the focal point of a convex mirror.

Answer 2

Concave mirrors are used in solar devices because concave is a converging mirror and it focus the light rays on a single point which results in convergence or capturing of light rays.
