. For an electron with KE = 1 eV and rest mass energy 0.511 MeV, the associated DeBroglie wavelength is 1.23 nm, about a thousand times smaller than a 1 eV photon. (This is why the limiting resolution of an electron microscope is much higher than that of an optical microscope.)
De-broglie waves tells about the wave nature associated with the particle.The de Broglie wavelength is the wavelength, λ, associated with a object and is related to its momentum and mass. Einstein showed that the momentum (p) of a photon is given by the formula.
At non-relativistic speeds, the momentum of a particle is equal to its rest mass, m, multiplied by its velocity, v. The unit of the de Broglie wavelength is meters (m), though it is often very small, and so expressed in nanometers (1 nm = 10(-9) m), or Angstroms ( ).
