Presentation Transcript

  1. 0 of 250 30 A photon in light beam A has twice the energy of one in light beam B. The ratio of A / B of the wavelengths is: • 1/2 • 1/4 • 1 • 2 • 4

  2. Monoenergetic electrons are incident on a single slit barrier. If the energy of each incident electron is increased the central maximum of the diffraction pattern: • widens • narrows • Stays the same • Depends on the speed of the electrons

  3. 0 of 250 30 Light beams A and B have the same intensity but A is longer than B. The photon flux (number crossing a unit area per unit time) is: • Greater for A than for B • Greater than B than for A • The same for A and B • Not enough info to decide
