Characteristics of thermal radiation

- Nov 02, 2019-

1. Any object, as long as its temperature is higher than 0K, will continuously emit thermal radiation to the surrounding space;

2, can be spread in vacuum and air;

3. Accompanied by the transformation of energy forms;

4. Strong directivity;

5. Radiant energy is related to temperature and wavelength;

The emission of radiation depends on the temperature to the fourth power.
