3. Quantum Physics

Question 1

The photoelectric effect: illustrate and discuss the
classical predictions, the experimental results and their explanation given by Einstein in 1905.

Question 2

Illustrate how atomic models allow to explain the
discrete frequencies of the emitted and absorbed radiation.

Question 3

Discuss the Stern-Gerlach experiment and its implications

Question 4

Discuss how you would introduce the need and the implication of a quantum mechanical model of atoms in terms of the wave-functions and orbitals

Question 5

Discuss how you would introduce in classroom the experimental evidence for the existence of an intrinsic angular momentum (spin) of electrons, photons and neutrons, in analogy with the relation between orbital angular momentum and magnetic momenta
