I have a very quick question about the Homework set.  I am havinga hard
time finding the Doppler effect equation-Could you point me in the right
direction? 

Answer: The Doppler effect formula (also in lab #1) is:
Velocity of object / speed of the wave = (frequency change)/ stationary
frequency

I like your question! (See on the web)

The planck constant, h=6.62 x 10^-34 Joule x second, is the constant in
the equation

E= h f

or

E = h c / WL (Same thing!) 

It has a history, and is not very easy to conceptualize!

The unit for the Planck constant was originally derived by Max Planck, for
the "rainbow", or so-called Black-Body spectrum, but is most easily
explained with the early models of the atom by Niels Bohr.

Bohr assumed that the ground state of an atom has a fundamental unit of
angular momentum, and the excited states come at multiples of that unit.
This way bohr was able to explain the Rydberg constant (see lab #2) and
the spectrum of the hydrogen atom as the result of atomic transitions.
(see for example tutorial #1).

 The units are units of the planck constant are those of angular momentum -
kg m/s x m. That's the same as Joule x sec ( because units of work, a type
of energy, are kg m/s^2 x m = Joule).
