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.

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?

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

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

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.

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