Question

The use of reflector in the solar cooker is to
A) decrease efficiency
B) Create greenhouse effect
C) Increase efficiency
D) none of the above

Answer 1

The answer is C.

The reflector on the top of the solar cooker is used to focus the solar energy over the glass surface. The mirror reflects the heat energy in a confined area and increases the net input energy to the solar cooker.

Answer 2

The use of reflector in the solar cooker is to increase efficiency. (Option C)

• The reflectors are used on the top of the solar cookers.

• These reflectors,reflects the solar rays towards the main spot of the solar cooker. Basically, these reflectors are used to channelize the solar energy in the solar cooker.

• In this way,the solar energy input in the solar cooker increases a lot and the total efficiency of the solar cooker also increases.
