Black-body Radiation (Noun)
Meaning
The electromagnetic radiation that would be radiated from an ideal black body; the distribution of energy in the radiated spectrum of a black body depends only on temperature and is determined by Planck's radiation law.
Classification
Nouns denoting natural phenomena.
Examples
- Black-body radiation plays a crucial role in understanding the thermal behavior of objects and surfaces in various physical systems.
- The physicist studied black-body radiation to gain insights into the fundamental laws of thermodynamics and the behavior of matter at different temperatures.
- The Cosmic Microwave Background Radiation in the universe is an example of the residual heat of the Big Bang, emitting black-body radiation at a temperature of about 2.725 degrees Kelvin.
- In the laboratory, a test sample is heated until it emits black-body radiation, which is then analyzed to determine its temperature and other physical properties.
- According to Planck's radiation law, the distribution of energy in black-body radiation is continuous and depends only on the temperature of the radiating object.
