your blog saved my life :). but hope it would be better if u have chapterwise solution of physics
ReplyDeleteAlhamdullilah.
DeleteWill try later, but this is going to be after quite some time.
do you have 2015 past papers?
Deletei need help in question 5 2011 may june 23 9702 please do help
ReplyDeleteI don't plan to solve the practical papers right now. Maybe later (a lot of time later, actually).
DeleteI hope solutions for the other papers can help you.
its not a practical paper its Q5 of May/June 20011 varient 3 Theory section 9702/23
DeleteOk. Sorry, I misread question for 'paper'.
DeleteIts explained as solution 682 at
http://physics-ref.blogspot.com/2015/05/physics-9702-doubts-help-page-138.html
how do i find explanations for full papers on this site?
ReplyDeletehow do i find full physics paper explanations on this site?
ReplyDeleteA list of solved past papers is available at
Deletehttp://physics-ref.blogspot.com/2014/05/physics-9702-notes-worked-solutions-for.html
There is still more to be added
Q: Where, in a standing wave, do the vibrations of the medium occur?
ReplyDeleteA 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.
For a stationary wave,
DeleteNodes 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]
Please tell me whether ALL the points between adjacent nodes vibrate? And what about their phase difference?
DeleteYes, all points between adjacent nodes vibrates (excluding the nodes).
DeleteFor 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.
Thank you so much! Those are very helpful.
ReplyDeleteI'd like to know whether there are similar worked chemistry mcq's as well.
Not yet. Maybe in the future, I'll try to consider this
DeleteCan you solve Q24 in Nov 13 variant 12? Thanks.
ReplyDeleteCan you give the link of the solved pp of physics p1? I want all from 2004 onwards
ReplyDeleteGo to (its the second link at the top)
Deletehttp://physics-ref.blogspot.com/2014/05/physics-9702-notes-worked-solutions-for.html
Some papers are still missing, but you can specific the questions in those if you require help
Assalamualaikum .. plz upload june 2015 past papers for chemistry and physics even without solutions.. thank u in advance and may God bless you for the amazing work u do...
ReplyDeleteWslm. Sorry, but the files are not uploaded here. See if you can find them elsewhere.
DeleteThis is very helpful.
ReplyDeleteI 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!
I'll think about it. A-level is much more difficult though, and would take precedence.
DeleteCan you please solve 2002 October Paper 1 Q 22, 31, 34 and 35? Thanks
ReplyDeleteFor Q22, see solution 1059 at
Deletehttp://physics-ref.blogspot.com/2015/11/physics-9702-doubts-help-page-222.html
When will 2015 papers be up?
ReplyDeletesome of the questions are already explained. search for them.
DeleteI really appreciate all the hard work you put into this blog! Thank you so much
ReplyDeleteHey is there any easier way to locate the 2015 papers solutions? Thanks by the way for this blog it's god's gift to mankind.
ReplyDeleteNo problem.
DeleteGO 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
Thanks you guys, you have noooo idea what impact this life changing discovery of a blog (If that makes sense :D) has had on my revision for my final paper. God Bless!
ReplyDeleteuk whts not so cool ? Me finding this blog just one day before my exam!!
ReplyDeleteWhere were u during my entire A levels ?
we have been available for quite some time
DeleteHi, could you make a list of all the equations needed for AS and A2 Physics please?
ReplyDeleteAnd thank you for all your worked exemples! Keep up the good work!
Thanks.
DeleteMaybe later.
But still, I believe that these are only really valuable and worthy if prepared by the person himself
hello.
ReplyDeleteCould someone please explain june 2017 paper 13 question 22?
Thanks
Go to

Where and How can I post my doubts?
ReplyDeleteThrough the comment box anywhere except on
Deletehttp://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.
I know youre Zubair
ReplyDeleteRight?
Do you provide mathematics reference (9709) since I know chemistry reference is provided.
