black body radiation
Answers
Explanation:
A black body is one that absorbs all the EM radiation (light...) that strikes it. To stay in thermal equilibrium, it must emit radiation at the same rate as it absorbs it so a black body also radiates well.
A black body radiation is an energy.
Explanation:
The object on which radiation is absorbed absorbs all the radiation and does not reflect anything, that object is called black body.
As we read in the Preface to Radiation that radiation is incident on an object, it absorbs some parts and transmits some parts, but this is not the case in a black body, it absorbs the entire radiation incident on its surface,does not reflect anything.
Definition: Therefore, we can say that the black body is such an object that absorbs all the radiation incident to its surface, irrespective of the wavelength of the radiation.
