Welcome to the PHYSICS 5B Course Page--- (remember to reload...)
SUMMER READING: Ch 36 (this is a very interesting
chapter to read and explore on your own. It deals with cameras and
all that. You can e-mail me if you have questions)
Notes on the Final follow below...
The final will emphasis understanding, graphing
and problem solving; like the midterms.
--------------------------------------------------------------------------------
Special office hours for Friday and finals week:
---I will have office hours from 12-2PM on Friday,
and in addition a review session on Wednesday from 1:00 to 2:30 PM in Kerr 283.
Also, drop-ins are OK this week.

Here are some notes on the Final:
Notes for the final/ Course summary,
1. The statics problems are very good because they allow
interesting problems to be constructed. There is an infinite
spectrum of equations that can be created, but of course you only
need a few, so judgement is involved. This is the kind of thing
(exercising judgement) that humans are great at. For this problems
(problems like the double ladder one) it is good to really understand
conceptually what each equations is saying. It is important to understand
to understand the difference between the kind of information you get
by analyzing the whole thing together vs analyzing it after it is cut
in parts (usually 2 parts).
It is not very valuable to read over a solution to a statics problem
to see if you understand it. It is MUCH MORE USEFUL to sit down with
a balnk peice of paper and work out the solution to a statics problem
with no help of any kind. Solve it for several variations (of angles,
configuration, whatever...). Work your solution through to the end
(don't leave answers in terms of sin's... and see if the result makes
sense (agrees with yr intuition).
2. Fluid flow Bernoulli eqn stuff. This also lends itself to designing
cool problems. You know the equation. Make sure you understand what
it is saying, and that you can work problems starting with only a blank
peice of paper! There will definitely be problems on both fluid
flow and statics on the final.
3. Bouyancy. It is worth understanding. It is not hard.
There may be a problem on it on the final if a I can think of
a good one.
4. Waves; this is a big area. There will definitely be problems on
it. Standing waves of strings, standing pressure waves of tubes,
travelling pulses, wave propagation, pulse propagation,...
a. Standing waves of strings
b. Pulses on strings
c. wave equation (understand it), how to use it on functions, not how to derive it.
cc. Ability to discern transverse velocity (for a string),
or air flow velocity (for a pressure wave), and to relate it
to the equation for the wave.
i.e., y(x,t)=f(x,t)
what is dy/dt vs x ? (and some time, t)
d. pressure waves, open ended tubes closed ended tubes...
propagating pressure waves, boundary conditions for pressure waves (what happens if
there is a hole in the side of a tube to the pressure waves (like in a flute)
how is tha standing wave spectrum effected?)
e.combinations of more than one normal mode (standing wave).
5. Optics, simple ray tracing
reflection at plane or spherical mirrors.
principal rays for simple imaging. (see notes on webb)
diffraction from double or multiple slits (where are the maxima)
what does the pattern of maxima look like?
mutiple reflection from a thin film.
(Farbry-Perot) interference between the first and second surface
reflections for a free-standing thin film or a film coating on glass.
refraction, Snell's law, how it is related to slowing
down of the wave.
Applications of this to light or water waves.
Ability to construct analogies between light and
water waves.
Sound intensity problems, dB scale...
Doppler effect (simple ones, moving source or "detector" (person hearing)
