G. P. Thomson's Experiment of Electron Diffraction

In this section ofResonance, we invite readers to pose questions likely to be raised in a classroom situation. We may suggest strategies for dealing with them, or invite responses, or both. "Classroom" is equally a forum for raising broader issues and sharing personal experiences and viewpoints on matters related to teaching and learning science. De Broglie's hypothesis of the dual nature of matter was confirmed experimentally independently by Davisson-Germer and G. P. Thomson. But most of the textbooks (e.g. [1]) discuss Davisson-Germer experiment. In this article, G. P. Thomson's experiment of electron diffraction is discussed.
