How to use the wien's law peak wavelength calculator
Find the peak emission wavelength of a hot object. Enter temperature in the field above; the peak wavelength, total power per area are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- T — Temperature (K)
Worked example
With temperature = 5772 K, the calculator gives peak wavelength ≈ 502.0395 nm; total power per area ≈ 62.93859 MW/m².
Frequently asked questions
What is the formula for the wien's law peak wavelength calculation?
Peak wavelength (nm) = WIEN / T × 1e9. Total power per area (MW/m²) = SIGMA × T^4 / 1e6. Here T is temperature (K).
What inputs do I need for the wien's law peak wavelength calculator?
You need temperature in K. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
