Photon Energy

Equation and meaning

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

Photon Energy Where : E is the Energy In Electron Volt,e is the Electronic Charge,V is the Voltage,

Variables in this formula

E — Energy
Energy SI unit: J
hc — Hc
Enter this value unless it is the selected unknown.
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.
