The device that uses solar energy in the form of heat is
Open in App
Solution
The correct option is D Solar cooker
A solar cooker is a device which uses the energy of direct sunlight to heat or cook. A mirrored surface with high specular reflectivity is used to concentrate light from the sun on to a small cooking area. Depending on the geometry of the surface, sunlight can be concentrated by several orders of magnitude producing temperatures high enough to melt salt and smelt metal. Thus heat of solar energy is used in cooking with a solar cooker.
