Stellar physics · λ_max = b / T
Wien Peak Wavelength
The wavelength at which a blackbody radiates most intensely, by Wien's displacement law. The Sun peaks in green light at about 502 nm; hotter stars peak bluer, cooler stars redder.
Peak wavelength502.04nm
Formula: λ_max = b / T
Worked example
With the default inputs, wien peak wavelength evaluates to 502.04 nm — Sun (5772 K) → 502 nm (green). The validator recomputes this against the known value on every build, so the formula is checked, not asserted.
