How this service works
Blackbody radiation: Wien peak wavelength and frequency, Stefan-Boltzmann power per area, and total power for an area or sphere.
Output
Returns Wien peak wavelength in metres and nanometres, Wien peak frequency in Hz, the named spectral band of peak emission (e.g. infrared, visible), Stefan-Boltzmann radiant exitance in W/m², optional total radiated power in watts (if area or radius provided), the emissivity used, the Stefan-Boltzmann and Wien displacement constants, and a human-readable summary.
Example use cases
Stellar peak emission wavelength
“What is the Wien peak wavelength and peak spectral band for a star with a surface temperature of 30000 K?”
Human body infrared thermal emission
“How much power per square meter does a human body radiate as a blackbody at 310 K, and what is the peak wavelength of that emission?”
Industrial furnace total radiated power
“I have a furnace with a radiating area of 12 square metres running at 1400 K with an emissivity of 0.85 — what is the total power it emits and what is the peak emission wavelength?”

Endpoint
GEThttps://physics-calc.x402tookit.com/blackbody?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need precise blackbody radiation calculations — peak wavelength, peak frequency, spectral band, radiant exitance, or total emitted power — for any object whose temperature is known in kelvin. It is the right choice for astrophysics (stellar spectra), thermal engineering (furnaces, heaters), remote sensing (Earth/atmospheric emission), or any scenario requiring the full set of Wien and Stefan-Boltzmann outputs in a single call.
Side effects
- Temperature below 1 K or above 1×10⁹ K returns a validation error
- Missing required temperatureK parameter returns an error
- Non-numeric input for temperature, area, or radius causes a 400-level error
- Emissivity outside 0–1 range is rejected
- Network or payment (x402) failure results in no response
