    What do we need to know about diffraction ?
    Longer wavelengths diffract more

    Edit: For diffraction you don't need to know about frequencies that was just to help me memorise the wavelengths/frequencies lol

    Post your questions and problems here and we will help you out.

    That's great if you can do the maths really well, means you can do about 40% of the paper really well. Not that much work to put in

    yeah sure thanks. I only chose physics because i thought it was mostly maths so i could revise the night before and get a good grade( like I'm doing in my other subjects) but i was really wrong physics needs weeks of preparation lol

    Most of it by the way, is just maths and the majority of questions are really just about picking the correct formula and then just plugging the numbers in.

    You could probably pass it just doing the calculations lol
