Open in editor
LaTeX\lambda=\frac hp

Variables

  • Define every symbol and unit before substitution.
  • Check the domain, shape, and convention required by the formula.

How to use this formula

Relates particle wavelength to momentum.

Important notes

  • Verify assumptions and units before applying the expression.
  • Keep exact values until the final rounding step when possible.

Quick example

Use the de broglie wavelength with a small known example, then verify the result independently.

Applicability, worked calculation, and verification

Assumptions and domain checks

  • For the de Broglie Wavelength, verify assumptions and units before applying the expression.
  • For the de Broglie Wavelength, every denominator must be nonzero, and the numerator and denominator must remain correctly grouped.
  • Use dimensionally consistent units and the sign, coordinate, and reference-frame conventions stated for the problem.

Worked example

Input

Output

Use the de broglie wavelength with a small known example, then verify the result independently.

Common mistakes

  • When copying de Broglie Wavelength, keep the complete numerator and denominator grouped; a missing brace or parenthesis changes the result.
  • Verify the result of de Broglie Wavelength with a known case, inverse operation, dimensional check, or independent calculation before publishing it.
