Doctors use concave mirrors, in motor cars convex mirrors as rear view mirrors and in case of solar cookers concave mirrors to concentrate solar radiations.
it is used so that it does not allow the sun s ray to go out of the cooker
It is because black colour is a good absorber of heat
Usually mirrors or a large reflector traps the sun's heat and focuses it on the food.
concave mirror is a solar device
Scientists are currently using mirror telescopes in space that do not have to deal with light pollution and are more clear than lens telescopes to take pictures of the solar system. They are also using radio telescopes to try and discover extra terrestrial life.
convex mirror is not used in solar cooker since it form image inside the polished surface
A reflective one.
a plane mirror is used in solar cookers so that the heat reflected by the mirror to the cooker should be same as the light(heat) given out by sun. hope dat helped
The cooker is well insulated, so it stays hot.
concave mirror are the best as it collects the sunlight coming from infinity to a single point called focus.it produces intense heat to cook food easily.still using plane mirror on household level for solar cooker is foolishness.
Reflects the most light. May need to give more information to the question.
parabolic cooker.
A parabola solar cooker works the best and fastest
A solar cooker and a pressure cooker are two completely different ways of cooking. A pressure cooker can still use a heat source like a gas or electric cook top. A solar cooker is as the mercy of the heat of the sun and the contents will only cook as well as the amount of heat it obtains.
A panel cooker is a way of using solar power to cook an item. The advantage of using a panel cooker is that it is using solar energy and not electricity.
horace de saussure invented the first solar cooker bout the year 1797
Solar is a device which Run from sunlight
