Q. Who proposed dual nature of electron?

AMUAMU 2013Structure of Atom

Solution:

Dual nature of electron was first proposed by de-Broglie. He gave the following equation for the wavelength of electron. $ \lambda =\frac{h}{mv} $ He proposed that all mieroparticles like electrons, protons, neutrons etc. have dual nature i.e., both wave nature as well as particle nature. Interference and diffraction support the wave nature of electron. $ E=mc^{2} $ support the particle nature of electron. $ E=hv=\frac{hc}{\lambda } $ is de-Broglie equation, it supports both wave nature and particle nature of electron.
