A charged particle is accelerated through a potential difference V. If the voltage were doubled, what would be the ratio of the new de Broglie wavelength to the original value?
Answer to relevant QuestionsIn 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 ...Using the general guidelines for nuclear stability, explain why aluminum has only one stable isotope (27Al). In other words, why aren’t isotopes of aluminum, such as 28Al or 26Al, stable? A Geiger counter is not efficient. That is, the number of events it records is always smaller than the amount of ionizing radiation that enters it. Explain why the efficiency is not 100%. Complete the following nuclear decay equations by filling in the blanks: Calculate the time required for a sample of radioactive tritium to lose of its activity. (Tritium has a half-life of 12.3 years.)
