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: λ=h/p, where λ is the wavelength, p the momentum, and h Planck's constant. Part...

Compare the de Broglie wavelength of a baseball moving at 90.0 miles per hour (40.2 m/s) to that of an electron moving at 1.30x107 miles per hour (5.81x10 m/s) and an alpha particle with a speed of 3.40x107 miles per hour (1.52x10 m/s). Louis de Broglie Which region of the electromagnetic spectrum are each of these wavelengths near? A. Ultraviolet 10-8 to 10-7 meters B. X-ray 10-11 to 10 meters c. Gamma ray 10-16 to 10-11 meters Smaller 10-20 meters....
