Blackbody 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
- Blackbody radiation is one of the most well-known effects in physics, particularly when considering ideal objects with zero reflectivity and unit absorptivity.
- Researchers typically focus on studying blackbody radiation at specific wavelengths, focusing on distinct patterns to draw conclusions about a celestial object's temperature.
- Stefan-Boltzmann law gives a formula to determine the total power emitted per unit surface area of a black body, characterizing its blackbody radiation in relation to temperature.
- One crucial step in developing Planck's law involved applying statistical techniques to a simple harmonic oscillator in a field of blackbody radiation to reconcile a critical disagreement with the conventional approach of that time.
- As part of an experimental investigation into Planck's radiation law, the spectral distribution of blackbody radiation from the experimental set-up can be directly compared to the predicted results to gauge its accuracy.
