In general, a good absorbers of radiation are also good emitters. In commonsense, something that is should be a poor absorbers. For example, we dress a white shirt in summer. However, a experiment has done and shown that the radiation detected of black and white surface are very very close.For example,if the radiation detected of black surface is 14.9, the white surface is 14.7. What is reason about this phenomenon? The experiment was used TD-8564A Radiation Cube that can be heated from room temperature to approximately 120 oC and the radiation detected is infrared.
