ideal radiator
  • an ideal body or surface that completely absorbs all radiant energy of any wavelength falling upon it with no reflection of energy, the temperature on the absolute scale being determined by measuring the intensity and spectral distribution of the radiated energy
  • an ideal body which would absorb all incident radiation and reflect none

Planckian radiator
  • hüpoteetiline täiuslik valguse neeldur ja energia kiirgur, millel ei ole peegeldusvõimsust
  • ideaalne keha, mis igal temperatuuril neelab kogu talle langeva elektromagnetkiirguse sõltumatult selle lainepikkusest
  • hypothetical perfect absorber and radiator of energy, with no reflecting power
  • idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence
absoluutselt must keha preferred
Usage examples
  • Absoluutselt musta keha poolt oma keskkonnaga termilises tasakaalus eralduvat kiirgust nimetatakse musta keha kiirguseks ja nimetus „must keha“ on antud seeläbi, et see neelab kõik valguse värvid.

black body preferred
Usage examples
  • The radiation emitted by a black body in thermal equilibrium with its environment is called black-body radiation. The name "black body" is given because it absorbs all colors of light.
