... What colour surface is best at absorbing infrared radiation? The aim of my experiment is to find out which colour absorbs the most infrared radiation. With these experiments I will test the hypothesis that the darker the surface of a material the more infrared radiation is absorbed. Infrared radiation, also called as "heat radiation" is an electromagnetic radiation that ranges from radio waves (an oscillation with frequency from 10kHertz) to gamma rays (an oscillation with frequency up to 1015GHertz) and includes visible, infrared and ultraviolet light. Electromagnetic radiation is a form of energy.

Light waves with different colour have different frequency (infrared is the slowest while ultraviolet is the fastest). Each body with a temperature more than the absolute zero emits electromagnetic radiation. The higher the temperature of a
