Glass sheet in a
and
Plane Mirror
solar Cooker ? mcq h​

Answer 1

Answer:

The plane mirror is used in a solar cooker, because it reflects the most of the light falls on it.

A glass sheet is used in a solar cooker because  the sun rays pass through the glass sheet cover and get absorbed inside the cooker box. It traps more and more heat rays of the sun, thus heating the food item

A concave mirror is used in solar cooker because it converges light rays coming from infinity to a point so that more heat is produced at the point sufficient to cook the food.
