Question 1 Report
Which of the following surfaces will radiate heat energy best?
Black surfaces will radiate heat energy best. This is because black surfaces absorb all wavelengths of light and reflect very little, which means they absorb more heat and therefore radiate more heat energy. White and light-colored surfaces reflect most of the incoming light, and absorb less heat energy. On the other hand, dark colors, especially black, absorb more light and heat energy, which makes them better radiators of heat. Therefore, black surfaces are considered to be the best radiators of heat energy among the given options.
