Wavelength of Electron
Introduction:
The wavelength of electron is a concept in quantum mechanics that describes the wave-like behavior of electrons. This phenomenon, known as electron wave-particle duality, was first proposed by Louis de Broglie in 1924. The understanding of electron waves has revolutionized our understanding of the microscopic world and has led to significant advancements in various fields such as physics, chemistry, and engineering.
