What was discovered

Wien deduces from thermodynamic arguments that the wavelength at which a black body emits most intensely is inversely proportional to its absolute temperature.

Wien was then working at the Physikalisch-Technische Reichsanstalt in Berlin, the same institute where Planck would soon formulate his complete radiation law.

What it led to

  • Estimation of stellar temperature from colour
  • Impetus towards Planck's black-body law (1900)
  • Nobel Prize in Physics for Wien (1911)
