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: \ =h/p, where X is the wavelength, p the momentum, and h Planck's constant. X = 1.06×10-34 Submit Correct m Previous Answers -14 As a comparison, an atomic nucleus has a diameter of around 10 m. Clearly, the wavelength of a moving baseball is too small for you to hope to see diffraction or interference effects during a baseball game. Part C Consider a beam of electrons in a vacuum, passing through a very narrow slit of width 2.00 μm. The electrons then head toward an array of detectors a distance 0.9540 m away. These detectors indicate a diffraction pattern,…
