Formula and methodology
Formula: lambda = h / p, where h is Planck's constant and p is momentum.
The de Broglie relation assigns a wavelength to a particle with momentum. It is a conceptual quantum-mechanics calculation; the result does not determine whether a laboratory instrument can resolve the wavelength.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Momentum — kg m/s; minimum 1.0E-40; maximum 10000000000
Worked example
| Input | Value |
|---|---|
| Momentum | 1.0E-24 |
Matter-wave wavelength is 6.62607015e-10 m.
Assumptions and limits
- Momentum is supplied in kg m/s and is treated as the quantity p in the nonrelativistic relation.
- Planck's constant is the exact SI defining value.
- No relativistic momentum conversion or wave-packet model is included.
