Hi again So I worked on this for a bit and have put it to the side for a while because I was happy with it; now I've come back and I'm short of confidence! Essentially what I've ended up with is the magnitude of the resultant pattern (phi) to be equal to... (some constant) * sqrt( (sin(d1) +...

Cheers for this; I found another page just after posting that mentioned a similar method for deriving 2 slits and I think I've managed to extend it to 4. I'll run through what you've said and make sure it all gives the same results. As you said, the phasors part of it was most important, which...

Thanks for the help! I've tried following some derivations through, and I've struggled to make the adaptation to uneven slit separations. I've come up with something though, but through a slightly different method. It seems to give roughly the right pattern for equal spacings, and an unequal...

Hi all I can't find any guidance on this on the internet, so hopefully someone here can help! Basically, I want to work out the intensity profile produced by a multiple slit experiment, with 4 slits. No problem there, but I need the separation between slits to be unequal! I've found mention of...

Thanks for the reply! That makes sense but I'm struggling to work it out in my head properly. The main ones required are beta minus and beta plus decays. In beta minus, with this diagram http://www.barnsley.org/penistone-grammar/science/Images/feynman_1.jpg the exchange particle is a W-...

Hi all Just a basic question really; I'm at university and have been tutoring someone through a couple of A level physics modules, and I'm covering some basic particle physics at the moment, which is all alright, but I've come to an issue with Feynman diagrams. Basically, for interactions...

Thanks all, like I said, so basic I don't really know what to say about it. I use that kind of thing so often but never have to think about exactly what it is that is seems I've just taken its existence for granted, but I should be able to get an answer out of it from the comments made.

I've got some maths homework to do over the summer before I go back to uni and there's this stupid question on there which is one of those 'so basic I don't know it' kind of questions, so here goes. Homework Statement What is LimΔx→0\frac{y(x+Δx) - y(x)}{Δx} ? The Attempt at a Solution...
