Blackbody / Wien's Law calculator
Peak wavelength & total exitance of a blackbody.
Category: Photonics
Formula: λpk = b/T · M = σT⁴
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Temperature | T | K | 5778 |
Result with the default inputs
- Peak λ: 501.5182 nm
- Exitance: 6.3201e+7 W/m²
Open it with your own values: put each input in the address as a parameter, for example /calculators/blackbody-wiens-law?T=5778. A unit other than the listed one goes in <parameter>_unit.
