Electronvolts to Nanometers Converter


What is 1 eV in NM?

1 eV in nanometers corresponds to the wavelength of a photon with energy of 1 electronvolt. Using the standard formula, 1 eV ≈ 1240 nm. This helps scientists, engineers, and students relate photon energy to visible and non-visible light.

How to Convert eV to nm

Converting eV to nm is straightforward. You can apply the formula manually:

eV to nm Formula

λ (nm)=1240÷E (eV)

Where:

  • λ\lambdaλ is the wavelength in nanometers (nm)
  • Eis the energy in electronvolts (eV)

Step-by-Step eV to nm Conversion

  1. Take the photon energy in eV.
  2. Divide 1240 by the energy value.
  3. The result is the wavelength in nanometers.

This eV to nm formula works for all photon energies in the electromagnetic spectrum.
