PHYS20180 Second Year Laboratory

This is the page for PHYS20180/PHYS20280 Second Year Laboratory.

Head of Lab was Prof. I.W.A. Browne. He has recently retired so we are waiting to see who replaces him.

Don't ask the demonstrator if your on friday, he doesnt stop talking about how easy the experiment is compared to how Hubble did it. I think he wants to bum him...but its a really good experiment :) and the lab report is good on it

 * The theory section on the the lab scrip is largely irrelevant.


 * When you are calculating the splitting of the sodium d line, you need an equation that isn't given on the script. If you ask the demonstrator they should be able to direct you to the right book but it's something along the lines of


 * $$ \Delta \lambda = \frac {\lambda \lambda'} {2(d_a-d_b)}$$


 * where $$ \Delta \lambda $$ is the splitting, $$\lambda$$ and $$ \lambda' $$ are the two wavelengths and $$ d_a-d_b $$ is the mirror displacement.


 * Don't worry too much if you can't find the white fringes and hence can't do the last part of the experiment. Most students can't find them (or at least out of those I've spoken to). You can always compensate by looking up alternative methods to look for the white fringes.
