Study Guide for Part IV

Ch. 8.2--8.5, Some parts of Ch. 9--  Central Forces &  Angular Momentum --- the Hydrogen Atom:

You have to know the difference between the approaches Bohr and Scrodinger used to deal with the hydrogen atom.
How do the results obtained by solving  the Scrodinger equation for the hydrogen atom compare eight that of the Bohr model?
What are the four quantum numbers associated with the electron in the hydrogen atom?
Given a radial wave function of the from given in Table 8,4 (page 280) be able to determine at which r adius  the probability for finding the electron peaks (i.e. becomes a maximum).. see you notes for an example.
Be able to write down the eigen values for the squares of L, j, S and L.S
Be able to explain how NMR is used in chemistry and Medicine.( See page 470-472)

Be able to calcul;ate energy released after fission or fusion using E = mc2
Be able to use the semiemprical binding energy formual ( eq. 137)

Be able to calculate ages of artifacts using radioactive dating? Read about C-14 dating and about determinig the edg eof he earth (page 493-495)
Be able to distinguish between fission and fusion. List some applications of fission and fusion reactions.

Ch:  15 Elementary Particles:

Print and Study the  the Standard Model and Beyond article
Be able to list the fundamental forces, know their relative strength, their range, and name the particles they exchange
What are the dozen or so fundamental particles that the Standard Model is base on?  
What do the abbreviations QED, QCD, GSW , SM etc.  stand for?
Study the Yukawa hypothesis (Section 15.3) it is a good model for demonstrating how forces are generated by exchanging bosons such as the photon in QED, the gluons in QCD, and the W and Z bosons in Weak Interactions.
What is the Four -Fermi Interaction? How does it differ from the GSW model?
Be able to define fermions, bosons, baryons, hadrons,leptons etc. Give examples for each
Be able to state the main idea behind String Theory?
