    Sorry about that - they should have been rectified now.
    How did you come by these?

    I'm doing these exams for my sins - my mocks went a lot better than I'd expected, but then last year's papers were quite nice. I wonder what AQA have in store for us...

    Looking forward to all the physics exams, with the exception of questions on waves.


    How's everyone doing with content - how much do you have left, if any?

    Just AC electricity I think.

    (Going off on a tangent, does anyone know why it is always written ac instead of AC? It really irritates me for some reason )

    Proving Young's Double Slit equation. Other than that, everything else is okay, I think. You?

    Waves is the worst topic in unit 2 in my opinion too. Diffraction gratings, why you do dis to me?!

    Haha, I've had to learn it all myself. I wasn't going to wait until one week before the exam - would be too risky, haha.

    What's your favourite topic?

    Hi Guys!
    Guys I got a few question with the January 2013 paper

    http://filestore.aqa.org.uk/subjects...1-QP-JAN13.PDF <- Paper

    http://filestore.aqa.org.uk/subjects...W-MS-JAN13.PDF <- Mark scheme

    Can someone explain 4Aiii) Where do they get the 1.63 x 10^-19 in the MS ... it seems as if I'm missing something quite simple out but can't figure out what :/

    6B) the table ... How did they get 2V for C-D

    Thanks

    Haven't got time to do 6B with you right now but you are right about 4aiii . youre missing something very simple. The energies given in the diagram are in eV. You must convert to J to do your calculation. 1J=ev * (1.6x10^19)
