We just started talking about it at school, and naturally i hav no idea what the teachers talking about! I was wondering if there are any good websites/videos online that explain it? Id be asking for a bit too much for a direct explantion from the physics buffs here :D cheeeers.

Hey guys, had my physics exam today and it went well, nothing on periods or air columns! so hopefully I've not screwed up and really nailed it to get a good A. thanks for ur help guys,it was invalueable. (Y) :D

Firstly what is a period and what's its relavence, and then I've had many questions asking me to draw what would be on an an osciloscope. With a certain time base and amplitude. Oh and slightly off topic, in the symbol for the electrical cell (---|i--) which one is the postive one and which one...

Thanks you guys, that really did help sort my probs out,iam starting to get my head around the questions. Hootenanny, that link was great, had exactly the practical applications i was looking for, and berkeman that's helped me picture what it looks like :D I had a look on that website if...

Evening, Ive been having some trouble with questions about fundamental frequencies and labelling nodes and anti nodes in an air column. for example :a tuning fork is placed above a glass tube and then the sound of the air column is adjusted by raising or lowering the glass tube in the...

thanks a lot ! that seems to hav cleared up some of my problems, ill do some exam Qs and see how it goes :D thanks hootenanny

Hello Iam stuck on a topic (have been for a while !) about the electro motive force around a circuit (emf). Iam also confused about how internal resistance plays a role in this. I do vaguely remember a teacher telling me that max current is at max internal resistance (or something around...
