28Marks Total ASSIGNMENT 14Compton, de Broglie, and Wave-Particle Duality(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 Scatteringa.
