Question

Name the type of mirrors used in the design of solar furnaces. Explain how high temperature is achieved by this device.

Answer 1

Concave mirror is used in the design of solar furnaces.As the parallel rays coming from sun,converges on focus and increases heat which leads to increase in temperature.By this,high temperature is achieved by solar furnaces.

Answer 2

Concave mirror is used in the design of solar furnaces.
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.
