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...
A particle has a de Broglie wavelength of 2.1 x 10-1°m. Then its kinetic energy increases by a factor of 3. What is the particle's new de Broglie wavelength, assuming that relativistic effects can be ignored? Number 1.62e-10 unitsym the tolerance is +/-2%
1. Calculate the de Broglie wave length for each of the following a. A proton with a velocity of 90% of the speed of light b. A 150. g ball with a velocity of 10. m/s
A proton in a particle accelerator is accelerated using voltage 6.53x106 v. Calculate the de Broglie wavelength of this proton in femtometers (fm, 1 fm = 10-15 m). = 1.01e-25 X fm
A “wavicel” (wave-particle-duality thingy) is confined to be in a very small but finite region of one dimensional space. (Interpret the confinement as the existence of walls that this thingy is never able to penetrate or overcome, while it is able to move in its allotted region of space freely.) (a) Calculated the expectation value of position (x) and its spread (Δx) for the first exited state of that thingy. Calculate now the expectation value for the momentum (p) and...
Part B The hypothesis that was put forward by Louis de Broglie in 1924 was astonishing for a number of reasons. An obvious reason is that associating a wavelike nature with particles is far from intuitive, but another astonishing aspect was how well the hypothesis fit in with certain parts of existing physics. In this problem, we explore the correspondence between the de Broglie picture of the wave nature of electrons and the Bohr model of the hydrogen atom. What...
