what experiment support debroglies equation
Answers
Answer:
the validity of de Broglie’s proposal was confirmed by electron diffraction experiments of G.P. Thomson in 1926 and of C. Davisson and L. H. Germer in 1927. In these experiments it was found that electrons were scattered from atoms in a crystal and that these scattered electrons produced an interference pattern. The interference pattern was just like that produced when water waves pass through two holes in a barrier to generate separate wave fronts that combine and interfere with each other. These diffraction patterns are characteristic of wave-like behavior and are exhibited by both matter (e.g., electrons and neutrons) and electromagnetic radiation. Diffraction patterns are obtained if the wavelength is comparable to the spacing between scattering centers.
Answer:
The experiment performed by Davisson and Germer supports the de-Broglie's concept. It was observed that wavelength of the electron wave as determined from diffraction experiment was in agreement with the wavelength calculated by applying de-Broglie'e equation.
