Phys 4910 Spectroscopy
Spring 2018 Assignment 10
This should be regarded as a writing assignment for the WP
component of this course. As such it should answer the question(s) completely,
concisely, and clearly. It should also be your own writing. You can look
up the answers (either on line or from your notes) but your submission
should be in your own words. Formulae are not needed, in fact shouldn't
be included. The answers are descriptive, not quantitative.
Explain qualitatively what is meant be the concept of perturbation
theory? How is it used?
