Name the type of mirror used in the following situation and support your answer with a reason:

$(a)$ Solar furnace
(CONCAVE MIRROR) Concave mirror.
Concave mirrors are converging mirrors. They are used in solar furnaces because they converge the parallel rays of sunlight incident on them to a single point,known as the principal focus. This concentration of light energy produces a large amount of heat at that point,which is useful for heating purposes.
