The Advanced Higher Physics thread

the exam is next friday. Hopefully it'll go better than maths did for me.

Discuss problems and the like here. The marking instructions seem fairly harsh. For example I just did a question on young's double slit experiment. I divided by the no. of slits rather than the slit seperation and lost 1.5 marks. :frown:

Advice - remember that doing past papers alone will probably get you a good mark, but in order to truly do well there is no substitute for understanding all the underlying physics, not just the processes you go through in order to answer the questions.

Any questions feel free to ask :smile:

When two rays of light are reflected (both undergoing a phase change) is the optical path difference (m+1/2)Y for constuctive interference ?
Or do they cancel out and it reverts to (mY) for constructive interference.
