I don't know cause those are the only ones my teacher gave me and he said, when i asked him if there was more, that that was all! I'm so lost... :/
Ow god these exams are soo nerve wrecking, lol hopefully whatever comes tommorow well all find easy and ace it. lol wishfull thinkng wont hurt

Hahaha amen to that. Either we all find it easy and ace or all find it hard and fail and they lower the grade boundary :P

Check the first page, avipsita posted a list of all the experiments, and a link on how to conduct them.
Thanks....What about the procedures...??? Anybody have that?? please.... I have only some....

Do you have the marking scheme??? and what exactly is your doubt about that graph??

Guys, I have a book called Edexcel Physics for AS written by Mike Benn and Graham George. It's really good and covers all experiments from mechanics to electricity(about 34). If any of you can get the book now, don't hesitate.

can u scan this book and upload it.. it would b really helpful coz where i live i cant get these books

the book is like 200 pages long. I don't have a scanner. Hard luck. The links given in this thread are really good. The experiments are similar to the ones in the book.

I'm sorry I did that d part tonight only but now my mind's washed :s and here I couldn't write it in such a way so that you could understand........its just that you'll have to compare the equation given with y=mx+c....You can do jan2011 3B paper question 8 b part , I hope that will make things bit clear......
e part you'll just have to calculate the gradient...(V2-V1)/(f2-f1)
Plank's constant is h and multiply the gradient with e(electron charge), photoelectric effect,right???
I also don't understand f part of that question....

And my explanation isn't good enough, I know... I know the method but its damn difficult for me to explain physics......

Its ok..I got the examiner report n understood it from there! Thanks for the help

Go through the practicals of the textbook
learn the graphs with their gradients n intercepts thoroughly..calculate uncertainities n their %age ..
do learn the values of micro, kilo n etc etc such as 10^-3 n others like this..
Learn the differences bw analogue n digital apparatus.

cx i learned all this stuff..Bt im still not satisfied..hahh..Lets see what happens tomorrow! :P
