A) de-Broglie
B) Einstein
C) Bohr
D) Heisenberg
Correct Answer: A
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. \[E=m{{c}^{2}}\] 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.
