Wien's Law Calculator
λ_peak = b / T
How to Use This Calculator
1
Enter temperature
Provide T in kelvin.
2
Calculate
We compute λ_peak and the corresponding frequency.
Formula
λ_peak = b / T, b ≈ 2.897771955×10⁻³ m·K
About Wien's Law Calculator
Estimates the peak emission wavelength of a blackbody at temperature T.
Frequently Asked Questions
Is this exact peak?
Yes for the spectral radiance vs wavelength curve; peak vs frequency differs.
Does emissivity affect λ_peak?
No; emissivity scales intensity, not the peak location for a gray body.
