Question
To understand de Broglie waves and the calculation of wave properties. In 1924, Louis de Broglie postulated that particles such as electrons and protons might exhibit wavelike properties. His thinking was guided by the notion that light has both wave and particle characteristics, so he postulated that particles such as electrons and protons would obey the same wavelength-momentum relation as that obeyed by light: ?=h/p, where ? is the wavelength, p the momentum, and h Planck's constant.PART A: Find the de Broglie wavelength ? for an electron moving at a speed of 1.00 To understand de Broglie waves and the calculation of wave properties.

PART A: Find the de Broglie wavelength ? for an electron moving at a speed of 1.00
Explanation / Answer
A)wavelength=h/p=h/(mv)=6.626*10^-34/(9.11*10^-31*10^6)=7.27*10^-10m
B)wavelength=h/(mv)=6.626*10^-34/(0.143*44.2)=1.05*10^-34m
