    I'm doing A-level AQA physics and we had a test on waves.
    I understood polarisation and so forth, but I didn't understand the maths of it.
    In our test, none of it looked like what we had been taught, or what was in the text book and I'm really afraid he will spring a retest on us and I have no idea how to do any of the stuff I got wrong.

    Can you help explain it to me?
    Do you know any websites that will help?
    Do you know where to find any questions?

    Pretty doubtful anyone can understand the problems you're having from that description...

    What was in your test and what had you been taught previously?
