Short Essay Questions
1. What is the relationship between wavelength, frequency, and a wave's minimum energy?
2. Describe the structure of an atom.
3. How does string theory reconcile quantum mechanics and the theory of general relativity?
4. Describe some of the problems with uniting quantum mechanics and general relativity.
5. State Newton's law of gravity.
6. What are strings composed of?
7. Referring to the experiment described in question Short Essay #6, what would the three observers see according to the theory of special relativity?
8. According to Einstein's theory for the photoelectric effect, what is the relationship between the frequency of light and the electrons ejected by the metal?
9. Adam is in his spaceship, at rest, when Ben's ship passes by, moving at nearly the speed of light. Adam observes that Ben's ship seems to be shorter than normal, and the clock on the outside of the ship is running very slowly. When he tells Ben about this, Ben claims that his ship was at rest, and that Adam passed him at nearly the speed of light. Ben also claims to have seen the same unusual problems with Adam's ship; it appeared shorter and its clock was running slowly. Adam and Ben's observations are both perfectly valid. Why?
10. Describe Max Planck's solution to the infinite-energy problem.
