what I need to know in 10 hours | 2005-06-05 19:48:05 ET |
these are all the posible topics that could be on my Electrodynamics final in the morning
1. poynting Vector, conservation of momentum & energy {stress tensor}
2. waves
- cosine or exponential form (switching back and forth)
- polarization (transversality)
3. waves in media (phase and group velocities)
- boundary conditions
- dielectrics & conductors
4. wave guides (modes, cut off frequencies)
5. reflection, refraction at interfaces
- absorption
6. potentials
- understanding how to get equations for V and A from Maxwell’s eqn.s
- solutions
- retarded potentials
7. radiation
- electric and magnetic dipole radiation
- interest in 1/r behavior of fields
- be able to compute P.V. and energy flow
8. relativity
- Lorentz transforms
- time dilation
- four vector notation
- invariance
- collision problems
9. relativistic notation for E&M
I am soo doomed! Doomed like salt!
