Exam

The exam will take place on Friday, 26 October, between 14.00 and 19.00 in Sparta, hall D.

As a preparation for the exam, you should look at the following things:

  • hand-in problems,
  • labs,
  • practice questions below,
  • reading according to the List of subjects and reading suggestions (you *don't* have to read all the books, choose a book that suits you - but remember that you (in principle) have to cover all topics),
  • homework according to this page.

In the exam, there will be exercises in which you will be asked to describe a topic (experiment, outline of a theory, physical models, etc.). There will also be exercises where you will have to calculate, similar to what you have done in the hand-in problems, and there will be exercises in which you will have to interpret physical data. No detailed derivation will be required (e.g. of the solution to the Schrödinger equation of the hydrogen atom), but you should know the starting point (e.g. Schrödinger equation), ansatz (e.g. separation of wave function into a radial and an angular part), and principal solution (e.g. that the solution to the angular Schrödinger equation of the hydrogen atom are the spherical harmonics and that the hydrogen energy is -13.6 eV / n2).

Suitable literature

  • W. Demtröder, Atoms, Molecules and Photons, Springer, 2006, available as e-book from the University Library
  • S. Andersson, F. Bruhn, J. Hedman, L. Karlsson, S. Lunell, K. Nilson, & J. Wall, Atom- och molekylfysik, Uppsala universitet
  • H. Haken & H. C. Wolf, The Physics of Atoms and Quanta, Springer, 2005 (or earlier editions), available as e-book from the University Library
  • A. Thorne, U. Litzén, & S. Johansson, Spectrophysics
