5 Ιουν 2019 · This example problem demonstrates how to find the wavelength of a moving electron using de Broglie's equation. While an electron has properties of a particle, the de Broglie equation may be used to describe its wave properties.
Example 5. Calculate the de Broglie wavelength of an electron of kinetic energy 500 eV. Solution: The kinetic energy of an electron 500 eV means the electron is accelerated by the potential 500 V. So, the de Broglie wavelength associated with the electron, λ = \(\frac{12.27}{\sqrt{500}}\) = 0.55 Å

22 Ιουν 2023 · In 1924, French scientist Louis de Broglie derived an equation, known as the De Broglie Wavelength Formula, that described the wave nature of any particle. Thus, establishing the wave-particle duality for the matter.
De Broglie Wavelength Formula is used to calculate the wavelength and momentum in any given problems based on this concept. Solved Examples Question 1: Find the wavelength of an electron moving with a speed of ms-1.
Hence we can verify the de Broglie equation if we observe the motion of an electron. This was done in the Davisson and Germer Experiment. Solved Examples For You. The de-Broglie wavelength of an electron (mass 1 × 10 − 30 k g, charge = 1.6 × 10 − 19 C) with a kinetic energy of 200 e V is: (Planck’s constant 6.6 × 10 − 34 J):
