De Broglie Wavelength

Equation and meaning

\[\lambda = \frac{h}{mv}\]

De Broglie Wavelength Where : λ is the Wavelength,K is the Kinetic Energy,h is the Plank's Constant,m is the Mass,

Variables in this formula

h — Height
Height SI unit: m
lambda — Lambda
Enter this value unless it is the selected unknown.
mv — Mv
Enter this value unless it is the selected unknown.

How to use this calculator

  1. Leave one value emptyThe empty field is automatically treated as the unknown.
  2. Enter known values and unitsChoose N, kgf, dyn, SI or another compatible unit when available.
  3. Review the automatic answerThe result appears immediately and is substituted back into the formula to check the residual.
