Objectives

After studying the material of this chapter, the student should be able to:
1. Describe the method used by J. J. Thomson to determine the ratio of the charge on an electron to its mass.
2. Describe the apparatus used and solve problems involving a charged particle passing undeflected through a velocity selector.
3. Use Wien's law to determine the peak wavelength emitted by a black body at a given temperature.
4. Describe Planck's quantum hypothesis and calculate the energy of a photon at a given frequency or wavelength.
5. State the experimental results of the photoelectric effect and use the photon theory to explain these results.
6. Use the photon theory to determine the maximum kinetic energy of photons emitted from the surface of a metal or the threshold wavelength for the metal.
7. Use the photon theory and Compton's hypothesis to calculate the wavelength of a photon after it has been scattered as a result of a collision with an electron.
8. Use E = mc2 to determine the minimum energy required for pair production.
9. Explain the significance of the Principle of Complementarity.
10. Use de Broglie's hypothesis to determine the wavelength of moving particle.
11. Describe the apparatus used in the Rutherford scattering experiment and describe the experimental results.
12. Describe Rutherford's model of the atom and list two problems with the model.
13. Write the Balmer equation and use the equation to determine the wavelength of a photon emitted as an electron drops from a higher energy level to a lower energy level. Determine the frequency and energy of this photon.
14. List Bohr's postulates and use these postulates to explain the emission spectra produced by the hydrogen atom.
15. Determine the Bohr radius and angular momentum of an electron in a given energy level.
