Hint: A parabolic shaped reflector is used in a parabolic solar cooker to generate heat from the sunlight. The container of food that has to cook must be placed at the right place so that all rays that are going to fall on the solar cooker can meet one point and create a large amount of heat.
Note that, in a mirror the point where the rays converge after reflection is called the focal point of the mirror.
Complete step by step answer:
Sunlight comes into the dish and is reflected back up to a centre focal point.
The focal point is placed in the central focal point at the cooking vessels.
The concentrated UV rays reach extremely high temperatures of \[500^\circ F{\text{ }}\left( {260^\circ C} \right){\text{ }}-{\text{ }}700^\circ F{\text{ }}\left( {371^\circ C} \right)\] that are capable of frying, and grilling.
Concave mirrors are used in solar cookers. This is because they are the only type of mirror that reflects sunlight to a single focal point.
In the case of a convex mirror, it will not work properly because they do not have a focal point in your cooker.
It will not work since In a parabolic solar cooker, the container of cooking is placed at the focal point of the mirror so that all rays that are falling on the solar cooker can converge to one point and produce large amounts of heat energy.
Hence, the correct answer is option (B).
Additional information:
The energy of direct sunlight to heat, and also the cook and other food materials used in the solar cooker is a device.
Nowadays, we have to use many solar cookers currently in use that are relatively inexpensive, low-tech devices and advanced, large-scale solar cookers can cook for hundreds of people.
Because they use no fuel and cost nothing to operate, the many nonprofit organizations are promoting their use worldwide in order to help reduce fuel costs and air pollution, and to help Slow.
Note:
• Reducing deforestation: Since 2.5 billion people cook on open fires using biomass fuels, solar cookers could have large economic and environmental benefits.
• When solar cookers are used outside, inside heat does not contribute potentially saving fuel costs for cooling as well.
• Any type of cooking may evaporate grease, oil, and other material into the air, hence there may be less clean up.
• Reduces your carbon footprint by cooking without the use of carbon based fuels or grid Electricity from traditional sources.
