Yeah I remembered to do that, although the shift for 1000km/s is hardly noticeable anyways.

Ok I see what he is asking now... he just wants the blackbody graph in this range.

Hello all, I am currently doing a 3rd year Astronomy and Astrophysics course and I am having some trouble with the current problem set (this is mainly because our teacher doesn't really teach us anything but that's another story). This is the question in particular that is bothering me...

Ok I'll try to do that and let you know. And my course is being taught by Erich Poppitz.

Problem Set: http://www.physics.utoronto.ca/%7Epoppitz/hw2.pdf I'm having a problem with I.3 I got I.1 (answer is given on sheet) For I.2 I found T(N,U,B) the following way T = \frac{\tau}{k_B} \frac{1}{\tau} = (\frac{\partial \sigma}{\partial U})_{N,V} \therefore T(N,U,B) =...

The problem set can be found here: http://www.physics.utoronto.ca/%7Epoppitz/hw1.pdf I am mainly having a problem with question II Part 2. Here's what I have so far: II) 1. Since the probability that a given molecule is in a subvolume V is \frac{V}{V_0}. It follows that the mean number of...

Given equations: \frac{d T^4}{dr} = - \frac{3 \kappa \rho}{a c} F_{rad} where a = 4 \sigma_{B} / c with \sigma_{B} being the Boltzmann constant. Also, define the optical depth \tau = \int \kappa \rho dr Optical depth measured at ground level is \tau_{g} Where \tau_{g} = \int^\infty_{ground}...

Ok the first part helped, I see what I did wrong, as for the rest of it I did something similar to what my professor showed us. We learned that: P_n = |A_n|^2 And to find A_n you have to do the following: A_n = \int^a_{-a} \psi(x) \psi^*_n dx where \psi^*_n = A (a^2 - x^2) sin(\frac{n \pi...

Hello all, I just ran across this forum thanks to google and decided to register and ask for some help on my homework! I'm in 2nd year university and we have a problem set due on Friday and this is the question on it: I started to do part a) but it seems very wrong. What I did was try to...
