Solution
A
solar cooker uses heat of the sunlight to
cook and heat food. A mirror is used in order to reflect and focus
sunlight at a point. A concave mirror is used in a solar cooker for
this purpose. The mirror focuses all the incident sunlight at a
point. The temperature at that point increases, thereby cooking and
heating the food placed at that point.
