The cover of a solar cooker is made of glass because:
Verified Answer
A. Glass allows sunlight into the container but does not allow heat radiation out of it
B. Glass is transparent and one can see the food cooking
C. Glass does not absorb heat radiation and so no wastage of energy
D. Glass is a good conductor of heat and is also cheap
Explanation:
Glass is transparent to short-wavelength solar radiation, allowing it to enter the cooker. However, it is opaque to the longer-wavelength infrared radiation (heat) emitted by the heated interior, trapping the heat inside and raising the temperature (greenhouse effect).
