ASSIGNMENT 14 Compton, de Broglie, and Wave-Particle Duality This assignment is worth 28 marks. The value of each question is noted in parentheses in the left margin. Note: The answer areas will ex... pand to fit the length of your response. 1. (1) There are similarities and differences between the Photoelectric Effect and Compton Scattering. Complete each of the six partial statements below using the following guide; all you need to provide for an answer is PE, CS, BOTH, or NEITHER.  PE if the statement only applies to the Photoelectric Effect  CS if the statement only applies to Compton Scattering  BOTH if the statement only applies to both the Photoelectric Effect and Compton Scattering  NEITHER if the statement applies to Neither the Photoelectric Effect or Compton Scattering a. Energy is conserved in _____. (1) b. Photons are observed before and after the interaction in _____. (1) c. Electrons are observed as the result of the experiment in _____. (1) d. Angles are measured in the experiment in _____. (1) e. Photons with very low energies such as 5.0 to 10.0 eV is observed in _____. (1) f. Ionization occurs in _____. Answe r: both (2) 2. What quantity measured in the Compton effect experiment show the wave-particle duality of light? Answe r: In the Compton effect experiment, the momentum shows the wave-particle duality of light as the momentum is delivered differently as a wave and as a particle. This means that there is a difference, particularly in the momentum. (5) 3. An X-ray with a frequency of 3.74 × 1020 Hz is incident on a thin piece of metal. The lower frequency X-ray on the other side is observed deflected at 48o. What is the frequency of the deflected X-ray? Answe r: (5) 4. A scientist changes the frequency of an incident X-ray to 4.50 × 1019 Hz and measures the deflected X-ray frequency of 4.32 × 1019 Hz. What was the angle of deflection? [Show More]
