Formula and methodology
Formula: Wavelength=Planck constant×speed of light/photon energy.
The inverse energy-wavelength relationship makes higher-energy photons shorter in wavelength.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Photon energy — J; minimum 1.0E-30; maximum 1.0E+15
Worked example
| Input | Value |
|---|---|
| Photon energy | 3.97289129E-19 |
Wavelength ≈500 nm.
Assumptions and limits
- Energy is positive and supplied in joules.
- The photon is in vacuum and constants are treated as exact planning values.
- Material dispersion, bandwidth, and wave-packet effects are not modeled.
