Photon Intensity-Electric Field

Equation and meaning

\[E_{n} = \frac{1}{2} \cdot varepsilon_{0} \cdot {E}^{2} \cdot c\]

Photon Intensity-Electric Field Where : I is the Intensity,ε0 is the Permebility of Space,c is the Speed of Light,E is the Electric Field,

Variables in this formula

c — C
Enter this value unless it is the selected unknown.
E — Energy
Energy SI unit: J
E_n — E N
Enter this value unless it is the selected unknown.
varepsilon_0 — Varepsilon 0
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.
