Contribution grade

Thermal radiation and spectral scaling · Thermal radiation and spectral scaling

Reference score140,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Constrains full temperature-dependent equilibrium spectra through reversible compression/Doppler reasoning, preserving a constant wavelength-temperature coordinate and appropriate spectral-density rescaling.

Scientific scope

Constrains full temperature-dependent equilibrium spectra through reversible compression/Doppler reasoning, preserving a constant wavelength-temperature coordinate and appropriate spectral-density rescaling. The displacement/scaling relation concerns the stated equilibrium blackbody radiation and thermodynamic argument. It does not determine the complete spectral function or guarantee a model for arbitrary nonequilibrium emitters. The later 1896 exponential spectral proposal and Planck’s law are separate contributions.

Evidence
