Formula and methodology
Formula: nλ = 2d sinθ, so d = nλ/(2sinθ).
The equation relates wavelength, diffraction order, lattice-plane spacing, and the Bragg angle.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Wavelength — same length unit; minimum 1.0E-6; maximum 1000000
- Diffraction order — minimum 1; maximum 100
- Bragg angle — degrees; minimum 1.0E-6; maximum 89.999999
Worked example
| Input | Value |
|---|---|
| Wavelength | 0.154 |
| Diffraction order | 1 |
| Bragg angle | 30 |
Lattice spacing = 0.154 length units.
Assumptions and limits
- Wavelength and spacing use the same length unit.
- The angle is the Bragg angle in degrees and order is a positive integer.
- Peak identification, instrumental broadening, and crystal structure are not inferred.
