Photon Momentum

Equation and meaning

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

Photon Momentum Where : E is the Energy in Electron Volt,λ is the Wavelength in Angstrom,

Variables in this formula

E — Energy
Energy SI unit: J
h — Height
Height SI unit: m
lambda — Lambda
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.
