Triple

Target entity: Planck's radiation law
Context triple: [Wien displacement constant, relatedLaw, Planck's radiation law]

• A. Planck radiation law chosen
  Planck radiation law is a fundamental formula in quantum physics that describes the spectral distribution of electromagnetic radiation emitted by a black body in thermal equilibrium.
• B. Wien displacement law
  Wien's displacement law is a physical law that relates the temperature of a blackbody to the wavelength at which it emits radiation most intensely.
• C. Stefan–Boltzmann law
  The Stefan–Boltzmann law is a fundamental principle of thermal radiation stating that the total energy radiated per unit surface area of a black body is proportional to the fourth power of its absolute temperature.
• D. Kirchhoff's law of thermal radiation
  Kirchhoff's law of thermal radiation is a fundamental principle in thermodynamics stating that, for a body in thermal equilibrium, its emissivity equals its absorptivity at each wavelength.
• E. Wien displacement constant
  The Wien displacement constant is the proportionality constant that relates the temperature of a black body to the wavelength at which it emits radiation most intensely.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
