davisson and germer experiment @ candle academy Pakistan.
this is lecture 11 of chapter 18 Dawn of modern physics for class 12 Federal board and kpk board. in this lecture davisson and germer experiment is briefly explained.
Devisson and Germer bombarded the beam of electrons on nickel crystal to observe the structure, the scattered beam of electrons they observed was similar to that of bragg's pattern of X-Ray diffraction from any crystal. this observation led to the phenomena that the particles behave like wave and thus the de broglie hypothesis was confirmed by them.
important subtopics of the lecture are given below.
what is davisson and germer experiment?
historical background.
experimental setup used by davisson and germer.
working of the experimental setup.
wave particle duality.
