De Broglie wavelength, frequency and velocity - interpretation. Ask Question Asked 7 years, 11 months ago. Active 5 years, 7 months ago. Viewed 22k times These hypothetical matter waves will have appreciable wavelength only for very light particles. de Broglie wavelength of an electron . When an electron of mass m and charge e is accelerated through a potential difference V, then the energy eV is equal to kinetic energy of the electron.
This tells us that each particle has a wavelength.

· In 1924 physicist Louis de Broglie proposed that as Calculating de Broglie Wavelengths of Particles. (a) Calculate the de Broglie wavelength of an electron moving with a speed of 105 m/s and also that of an Louis de Broglie showed that the wavelength of a particle is equal to Planck's constant divided by the mass times the velocity of the particle.
DE BROGLIE WAVELENGTH IIT JEE - NEET 1) The de Broglie wavelengths of electron waves in two orbits is 3:5. The ratio of kinetic energy of electrons will be: (EAMCET 2009) a) 25:9 . b) 5:3 . c) 9:25 . d) 3:5. Logic: The wavelength, λ of electron wave can be expressed by de Broglie's equation:
In 1924 Louis de Broglie theorized that not only light posesses both wave and particle properties, but rather particles with mass - such as electrons - do as well. The above equation indicates the de Broglie wavelength of an electron. For example, we can find the de Broglie wavelength of an electron at 100 EV is by substituting the Planck’s constant (h) value, the mass of the electron (m) and velocity of the electron (v) in the above equation. Then the de Broglie wavelength value is 1.227×10-10m. Sample Problem: de Broglie Wave Equation.

This chemistry video tutorial explains how to calculate the de broglie wavelength of large objects and small particles such as electrons. It contains plenty
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.)
The wavelength of a particle, given by \lambda = {h\over p}, where h is Planck's constant and p is the momentum.
