# What is the wavelength of an electron of energy 25 ev ?

Jul 16, 2022

The wavelength of an electron with an energy of 25 eV is approximately 0.1 nm. This can be calculated using the following equation:

wavelength (nm) = h/sqrt(2mE)

where h is the Planck constant, m is the mass of the electron, and E is the energy of the electron.

Thus, the wavelength of an electron with an energy of 25 eV is approximately 0.1 nm.
