Learning Goal To Understand De Broglie Waves And The Calculation Of Wave Properties In 1924 Louis De Broglie Postulat 1 (27.86 KiB) Viewed 14 times

Learning Goal: 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: A h/p, where A is the wavelength, p the momentum, and A Planck's constant. Find the de Broglio wavelength A for an electron moving at a speed of 1.00 x 10 m/s. (Note that this speed is low enough that the classical momentum formula p= mu is still valid.) Recall that the mass of an electron is m=9.11 x 10 kg, and Planck's constant is A-6.626 x 10-4 J-8. Express your answer in meters to three significant figures.
