Question

Which radiations of sunlight are used in heating a solar cooker?

Answer 1

Solar cooker:

1. A device for cooking food by using the heat energy generated by the sun is called a solar cooker.
2. A solar cooker admits UV light rays before converting them to prolonged infrared light waves that cannot leave. Infrared light has the correct amount of energy to cause the water, fat, and associated proteins in food to shake and raise the temperature.

Advantages of using a solar cooker:

1. Solar cookers do not require any fuel.
2. Eco-friendly and cost-effective.
3. Cooking without carbon dioxide-based fuels reduces the carbon impact.
4. Cooking is both sanitary and healthy.

Disadvantages of using a solar cooker:

1. It would not operate in overcast conditions.
2. Solar cooking takes longer than stove-top cooking.
3. Solar cooker production is expensive.
4. Some thick items, including huge roasts and loaves of bread, are difficult to prepare.

Therefore, Infrared radiation from the sun is used to heat the solar cooker.
