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.
