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.
