Question

Name the type of sperical mirror used in solar furnace.Give 2 reasons

Answer 1

concave mirrorrs are used in solar furnaces to concentrate a large amount of heat

The shape of concave mirrors catches and directs the sun light inward which provides greater heat retention. This allows the heating system to achieve a higher temperature and be better suited to heat your entire home. A flat or convex mirror would reflect a lot of the light outward, thus making those shapes less efficient for gathering solar heat.
