Light, shiny surfaces are poor absorbers and poor emitters of radiation. This is why it is best to wear bright white clothes on a hot day as they reflect the heat and reduce absorption of the heat energy.
Thermal radiation is electromagnetic radiation generated by the thermal motion of particles in matter. Thermal radiation is generated when heat from the movement of charges in the material (electrons and protons in common forms of matter) is converted to electromagnetic radiation. All matter with a … See more Thermal radiation is the emission of electromagnetic waves from all matter that has a temperature greater than absolute zero.
