sci.blackbody-radiation Calculator
Calculates spectral radiance, total power, and peak wavelength of a blackbody from temperature using Planck's law and the Stefan-Boltzmann equation. Total radiated power scales as T⁴ — doubling temperature increases emission 16-fold, explaining why stars hotter than the Sun are vastly more luminous.
Inputs
Temperature K
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Wavelength Nm
Distance between successive wave crests. Related to frequency: λ = speed / frequency.
Results
peak wavelength (nm) - Wien
The computed linear length.
total power (W/m²)
The combined total across all inputs and components.
spectral radiance at λ
The value at the specified point or condition.
color at peak
The colour classification or output colour code computed from the inputs.
