True/False
The reflector used in solar cooker increases its efficiency.

Answer 1

Dear user,
It is true.
Use of Reflector :
Reflectors basically concentrate the light coming from the sun at a fixed point.As cooker has less
surface area,so using reflector is advantageous as well because it can concentrate whole of the
sunlight to a single fixed point.
Depending upon the geometry of the surface,high heat and temperature can be produced
for cooking or melting purposes.
