    1. I don't plan to solve the practical papers right now. Maybe later (a lot of time later, actually).

      I hope solutions for the other papers can help you.

    2. its not a practical paper its Q5 of May/June 20011 varient 3 Theory section 9702/23

  5. Q: Where, in a standing wave, do the vibrations of the medium occur?
    A only at nodes
    B only at antinodes
    C at all points between the nodes
    D at all points between the antinodes
    Answer is C but How? please explain. Thank you.

    1. For a stationary wave,
      Nodes are points of zero amplitude and antinodes are points of maximum amplitude.

      For stationary waves, the nodes are always stationary. This is a basic fact about stationary waves. [A is incorrect]

      Now, between 2 antinodes, a node can be found. So all points between the antinodes do not move since a node does not move. [D is incorrect]

      Apart from the nodes, all the other points move, not only the antinodes. [B is incorrect]

      Delete
    2. Please tell me whether ALL the points between adjacent nodes vibrate? And what about their phase difference?

      Delete
    3. Yes, all points between adjacent nodes vibrates (excluding the nodes).

      For a stationary wave, 'loops' can be seen to be formed. Within one loop, all the particles vibrate in phase and they are all exactly out of phase with all the particles in the adjacent loop.

      Note that in a stationary wave, vibrations are only up and down.

  6. Thank you so much! Those are very helpful.
    I'd like to know whether there are similar worked chemistry mcq's as well.

  10. This is very helpful.
    I am doing IGCSE, u guys have O-level and A-level, can u please try to solve IGCSE papers also in future. O-level and IGCSE are Quite similar, but it would be much helpful to IGCSE papers too!
    Please consider. Thankyou!

    1. I'll think about it. A-level is much more difficult though, and would take precedence.

    1. No problem.
      GO to google and type:
      9702 physics ref

      followed by the first lines of the question

      if the question has been explained, it should be available among the first results from the search

    1. Through the comment box anywhere except on
      http://physics-ref.blogspot.com/2014/05/physics-9702-notes-worked-solutions-for.html

      If it's from a past exam paper, given the reference and comment.

      If it's from a paper that has already been solved partly, it's better to comment there.

      Links to the past paper can be obtained from the link I just mentioned.

If it's a past exam question, do not include links to the paper. Only the reference.
