Black Body Peak Calculator — Formel
## Wien's Displacement Law
Wien's law states that the peak emission wavelength of a black body is inversely proportional to its temperature.
### Formula
**lambda_max = b / T**
where b = 2.8978 x 10^-3 m·K is Wien's displacement constant. Hotter objects peak at shorter wavelengths (bluer light).

Lösungsbeispiel
The Sun's surface temperature (~5778 K).
- lambda_max = b / T
- lambda_max = 2.8978e-3 / 5778
- lambda_max = 5.015e-7 m
- lambda_max = 501.5 nm (green-yellow visible light)
