Question

why are concave mirrors are used in solar devices

Answer 1

Hay mate here is your answer ✌❤☺


Concave mirrors are used in solarfurnaces, because concave mirrors are the only type of mirror that reflects light in toward a single focal point. A flat mirror 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.



Hope it will help you ☺❤
