(a) What is meant by the wave function of a particle?

(b) A beam of electrons passes through a single slit and a beam of protons passes through a second, but identical slit. If the electrons and protons have the same speed, which beam will experience the greatest amount of diffraction? Explain your answer.

(c) A proton is confined within an atomic nucleus of diameter 4.0 fm. Can we know with certainty if the proton is really at rest? Explain your answer.
