fuck I just typed this whole fucking thing then I accidently clicked back and lost it all.

So I'm typing it again.


Section 2 problem 2.
I took a look at it =) I had a thought about how to approach it but I might be totally wrong.

Going to type it out anyway.

This problem looks to me to be a dopler shift problem ( could be wrong )

Where the Frequency of the Observer is described by

Fequency of Observer = (Fequency of source)*(A+B)/(A-C)

Where A is the velocity of the waves through some material. Since the problem talks about light and vacuum it should be just the speed of light (c). (B) is the velocity of the observer, which when talking only about the X direction would be V*cos(theta). (C) would be the velocity of the source, which would be zero, since the source of the cosmic background radiation would be the glow from the bigbang(ish) era. Which shouldn't have a velocity.

Anyway, if you plug in all that stuff, you get the same thing equation they have, so it must work.

As for the other part, I guess they just want a velocity? you probably need a wave equation or something?

X(t) = Amplitude*Cos(wT+Phi)

w = angular velocity.

The maximum velocity would be (Amplitude)*(Angular Velocity)

could be it. again I shrug =D hope it helps you out, was just my half drunken nighttime musings. God I wish I had an awsome class like that.
Miss you man. Here's a link I found that you should click, brings back not so long ago memorys
CLICK THIS NOW!
