    Very happy with the paper, I found it alot nicer than AS1. Except a question or two but overall I am pleased.

    I think it was a nice paper but I ran out of time. I didn't like the drawing superposition question you had to do and some weird definitions that you had to write/i couldn't remember. I was so happy the big marker was lenses and not some big ugly one about wave particle duality or a lot more on medical physics.

    That wavelength one was a bit weird in the double slit experiment question which you had to calculate from the path difference.

    I was able to get them no problem. 3rd dark fringe has a path difference of 2.5(lamda) which equalled what 1.96 something? So (lamda) equals that number divided by 2.5 ... or thats how i done it atleast

    Did anyone get a phase difference of 60 for question 2/3 for those 2 waves on the graph? And does anyone have a copy of the paper?

    Yeah I divided the path difference we got by 2.5.

    I got 72. Teachers don't get the paper until 24 hours after the exam

    Did you get the angle of incidence to be 46.3 degrees? For the prism. People in my class got mixed answers.

    In our school the teachers often have the paper before the exam is even finished!

    I thought the paper was more difficult than AS1, but it wasn't too bad. I had no clue what the electron arrangement in lasers was though.

    Yeah I had no idea either, did anyone else have any idea? I just wrote about population inversion.
