Participating to Physics Reference blog

  • Participating to Physics Reference blog

The admin of 'Physics Reference' blog is pleased to inform you that you are welcomed to participate to the blog as from now. This initiative has been taken to provide the viewers with a wider variety of resources and this requires the participation of many.

You should consider the following if you intend to participate:

  • How can I participate?
You can participate by providing notes (full notes, chapterwise, concept, summary notes, revision notes, concept maps, ...), worked solutions (a complete paper to a single question - in the same format as those provided by Physics Reference), articles, research works, .... (anything that you think may help the others)

  • Levels
Your participation is not limited to A-Levels. It can be from O-Level, IGCSE, A-Level, University and any level that you wish.

  • Subjects
Again, the subject is not limited to Physics only. You are encouraged to help in whichever subject (science or not) you are confident. As for Physics worked solutions for A-Level, you may leave paper 1, 2 and 4 to the admin of Physics Reference, as has been the case before. You mat participate in any other than these 3 papers for worked solutions.

  • Some rules that you need to follow:
- You are not allowed to provide copyrighted materials. If ever i portion of text is taken from a book, ... a reference should be made to them.
- It should be TYPED in a Word document (softcopy), unless it's a diagram, illustration, ... Scanned pages are not recommended.
- Ensure that the information you are providing is correct, accurate and reliable.
- Include you name and country in the file so that the work is credited to you. The blog is viewed by people around the globe so I would like to properly credit anyone who has participated.
- Inform us which subject you will be working (through the comment box) on if you are willing to participate. This would prevent different people from doing the same work.
- The final work should be submitted to
- The admin of Physics Reference reserves the right to accept, reject (this usually won't be the case if your work is correct) or modify the content of your work so that it fits the viewers.
- After the work has been published, you are encourage to come back regularly to answer the queries of the viewers and clarify their doubts about your work.
- By participating, you are agreeing that the work is now a property of the admin of Physics Reference. You are not allowed to post the same work elsewhere online.

The 'Physics Reference' is being viewed by more and more people and the number of queries keeps on increasing. A single person won't be enough to help these viewers. It is hoped that many of you will participate and help the other readers.


  1. Which years do you need worked solutions for?

    1. you are welcomed to choose which paper you want to solve.

  2. What if you already have them posted?

    1. Don't do it again.

      But I would prefer if you could choose a subject other than Physics, since I'm doing physics.

  3. Hello, I do not know if this is the right place to ask this question, but I'd really be thankful if you could answer. What I'm confused about is AS Physics Paper 2. Could you please tell me how to determine the number of significant figures you need to give in the answer? Also, suppose in part a of a question, I find the value of x to 4 significant figures, but write it to 3 significant figures in the answer blank for part a. Now, if I need to use the value of x in part b, will I use the 3 sig fig value or the 4 sig fig value that I initially calculated. Thanks!

    1. See solution 1022 at

  4. Would you accept solutions for subjects of the commerce field?

    1. Of course, but you'll need to ensure that they are correct. I won't be able to verify since it's not my field.

  5. Hi
    is it possible to get the complete collection of physics mcqs in a zip or pdf file because there are more than 200 pages and it is hard to the specific Q

    by the way this site is a great resource for A level physics students as well as teachers
    I dont like the traditional A level books they are just teaching the basics and No indepth , even some just copycat the O LEVEL MATERIALS


    1. Thanks.

      Sorry, but I don't think that's possible.

      You could write the blog's name and followed by the question at google search. if it has already been solved, you should obtain a result from the search.

  6. salam, what if i send you the pictures of Alevels biology solved p5? will you accept it?

    1. Wslm. You are most welcome. It would help a lot of students. The email address is available up.

      Be sure to include your name so that the work can be credited to you.

      Just let me know through a comment here when you send the mail.

  7. Can you please explain what a signal generator is? It appears a lot in the papers especially p5 and I have no clue at all to what it can do. I searched the net but answers are too complex. i'd be grateful if you could help

    1. It's an apparatus that can produced (wave) signals of different frequencies. The user can select the frequency.

      For example, if connected to a CRO we can see the frequency of the waves changing when we change the settings on the signal generator.

      Or if connected to a loudspeaker, we can hear different pitches due to change in frequency.


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