Thanks a lot! The 4 equations I started with were The wavelength relationship I posted about above, and the following c(Gamma*mass(electron)*velocity(electron))cos(electron angle) + c*(h/lambda')cos(theta) = E0 (h/Lambda')sin(theta) = (Gamma*mass(electron)*velocity(electron))sin(electron...

I've given it a huge go and still no luck unfortunately. Am I using the right formula for the momentum of an electron, p= gamma*m*v? Also, could I get a hint as to what order I should solve the equations? :)

Alright thanks I'll see if I can finish it from here.

I had another read of my textbook and I think I found the "special relationship". I assume it's the relationship between incident wavelength - scattered wavelength and (1-cos(theta)). I put in hc/E in place of the incident wavelength and got a messy expression for the scattered one in terms of...

Homework Statement http://puu.sh/7Nw8T.png Homework Equations From what I've read in my textbook I believe I should be using the equations: Photon: p=E/c Electron: E(kinetic) = (Gamma-1)*m*c^2 p= (Gamma)*mass(electron)*velocity(electron) The Attempt at a Solution For the...

Omg... Wow thank you so much. I can't believe I overlooked that haha :P

I ended up with 299350496 metres per second. That sounds about right, at least it isn't impossible lol. Thanks a lot buddy.

Right, that makes sense. So the proper time is the given time, and I need to find the dilated time to calculate the velocity? Am I right in that if I find this dilated time, in the Earth's frame, and use it to divide 10,000 I'd get the velocity? If so, should I just use the t = tp*gamma formula...

I tried using the t = gamma*tp formula, but replaced v in gamma with 10000/tp and tried to solve for tp but couldn't get anywhere. Can someone please give me a hint?

I guess my biggest problem is this. The particle must have only experienced 2.197x10-6 seconds but then it's traveling faster than the speed of light in it's frame. Please someone help me understand this lol I don't know how to solve for v without having both the proper time and dilated time :|
