Study Questions - Idea 5 (Chapter 7) B. Ellman Section 005



(1) About when did quantum mechanics come into being?

(2) What were the experiments that presented serious difficulties for physics around 1900?

(3) What is the photoelectric effect?

(4) Suppose I shoot infrared light at a piece of sodium metal - what might you expect to see?

(5) What was Einstein's theory of the photoelectric effect? Define any new terms.

(6) What is an "atomic spectra"?

(7) What is the difference between the Bohr model of the atom and a model someone might have used in 1900?

(8) How successful was the Bohr model?

(9) How did Bohr explain the different color lines in spectra?

(10) What was de Broglie's contribution to the birth of quantum mechanics?

(11) How does the "de Broglie wavelength" depend on momentum?

(12) What is a wave function?

(13) What does the wave function tell one about an object?

(14) What is tunneling?

(15) Tunneling is pretty weird! Why don't we see it all the time in everyday life?

(16) How does Schrödinger's picture of an atom differ from Bohr's? Draw an atom as best you can within Schrödinger's picture.

(17) How well does Schrödinger's theory work as a physical description of the world? What about the extensions of Schrödinger's theory that include special relativity?

(18) What is the "g-factor" of the electron?

(19) How does de Broglie's early wavelength work relate to Schrödinger's complete theory?

(20) Within Einstein's theory of the photoelectric effect, how does a bright light differ from a dim one? How about a green light from a red one?
