Moderate

As the temperature of a black body is raised, the black body radiations become richer in:

Correct answer: C. Short wavelengths

  • A. Intermediate wavelengths
  • B. Long wavelengths
  • C. Short wavelengths
  • D. Low frequencies

Explanation

Wein's displacement law states that temperature is inversely related to wavelength. Therefore, increasing temperature results in shorter wavelengths.

About Dawn of Modern Physics

Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
