Hi everyone, AsSalamoAlaikum Wr Wb...
To get things organized in a better way, I am making this thread. As othewise, some queries remain unanswered!
So post your PHYSICS doubts in this thread. InshaAllah other people here will help me and you all.
NOTE: If any doubts in the pastpapers, please post the link! You can find links here!
Any Physics related notes and links will be added here in this post. Feel free to provide the links to your notes around the forum, or any other websites!
Thanks!
Jazak Allah Khair!

that saying in the end actually made me feel much better so thankyouSuggest why a thin rod can bend more than a thick rod without breaking.
Explanation required.Thanks in advance.
Oh.Welcome.that saying in the end actually made me feel much better so thankyou
I'm assuming it's a diffraction grating question as you have cut off the first part of the question AND the paper number -.-Helpp part 2View attachment 41810
Yeah if one fringe spacing occupies x mm(also the fringe spacing cause fringe spacing is from the center of one fringe to the center ifvanothervif I'm not wrong)) then how many fringes will occupy N mmI'm assuming it's a diffraction grating question as you have cut off the first part of the question AND the paper number -.-
Second order maxima, thus n = 2
substituting in dsin x = n times wavelength,
you get d.
now d is the fringe spacing. The number of fringes in 1m is 1/fringe spacing.
I'm sorry I can't exactly explain why but remembered something I learnt in primary school.
Like if 1 box is 5 cm, and a large box is 100 cm, how many boxes can fit in a large box or something like that...

And could you help me with that second questions b part?Yeah if one fringe spacing occupies x mm(also the fringe spacing cause fringe spacing is from the center of one fringe to the center ifvanothervif I'm not wrong)) then how many fringes will occupy N mm
u mean b(ii) ?http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s10_qp_21.pdf
can sombody please do question 5 (b) (iii)
Thanks in advance
Well that's the strength part.. The closer the field lines the stronger the strength..http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s10_qp_21.pdf
can sombody please do question 5 (b) (iii)
Thanks in advance
Well that's the strength part.. The closer the field lines the stronger the strength..
So that gotta be on the top.. Where they r close..
And constant is when the have equal distance btw them as in equal.. Strength
It is on the top, where the spacing between the field lines is greater.thanks alot for an answer
But can you please elaborate on how to find the decreasing field strength part?
Thanks again
It is on the top, where the spacing between the field lines is greater.
Yes, it can be either top or bottom.So can it also be on the bottom where the spacing is also greater??
Thank you
