An electron is accelerated from rest through a potential difference of 100 V. What is the de Broglie wave-length of the electron?
Answer to relevant QuestionsAn electron traveling at 3.00 x 104 m/s is further accelerated by a potential difference so as to reduce its de Broglie wavelength to one-third of its original value. How much voltage is required to accomplish this? Using a typical nuclear diameter of 4.25 x 10-15 as its location uncertainty, compute the uncertainty in momentum and kinetic energy associated with an electron if it were part of the nucleus. For energies greater than a few ...In the Rutherford scattering experiment, the minimum distance of approach for the alpha particle is given by Eq. 29.1. Explain why this distance does not necessarily represent the nuclear radius. Is it larger or smaller than ...Explain how the fusing of very light nuclei and the split-ting of very heavy nuclei can both release energy. Write the nuclear equations for (a) The alpha decay of 237Np, (b) The decay of 32P, (c) The decay of 56Co, (d) Electron capture in 56Co, and (e) The decay of 42K from an excited nuclear state to the ground state (not ...
