I dont think there'll be a standing waves thing in Sec. C this time, because there was in Jan.
doh, hopefully there is, cos thats one of the ones i know well :s:
good luck everybody for tomorrow. I'm taking both UP and FA as resits again. :rolleyes:

Hope thats right. I'm useless at standing waves. If one does come up I'm going to do the one with the tube that you place half in half out of water. :rolleyes:

I wish I got a pink booklet telling me what to revise. The one I had only has information on a topic we will be questioned on for PART of the paper
lol, u can basically judge what they are gonna ask from the booklet!

What do you do for it?

Kundt's Tube? An Organ Pipe? A String?

Does anyone know what sections Cs came up for the physics in action paper in jan 2005? Anyone got any predictions on what the section Cs could be for PIA this time round?

You shouldnt worry about that. Wave superposition and the quantum observation are always favorite ones that they ask (for paper 2).

But you can relate most of the topics to your coursework that you did. (I did a sensing, a superposition on string and a research report on materials last year).

You are lucky doing OCR B physics. It is very easy to get a good grade.


edit: stunt girl, did you sit the "Rise and fall of the clockwork of the universe" paper in january?

Thanx for your help, but I'm not doing paper two. I'm resitting only physics in action to increase my marks. So, does anone know what came up in section C in PIA in Jan 2005 or have any predictions of what may come up this year?

Oh and yes, I did take the 'Rise & Fall of the clockwork universe' paper in jan.

Jan 2005 was Imaging and Materials.

Anyone got a pic of glass' internal structure? Need a scale for it as well and reasons as to why glass being brittle and transparent (or having a low refractive index) are due to it's internal structure.

theres a pic of internal structure of glass on pg 107 of the advancing physics as text book, it also goes on to explain the transparency in terms of amorphous structure etc

Hi, just read through the thread. doing my exam tomorrow and a bit worried about the following things now, could somebody PLEASE answer these for me;

1.What is the formulae for the standing wave experiement with the frequency generator?

2. What is the ULTRA VIOLET CATASTROPTE effect to do with quantum behaviour?

Thanks

Cheers SunGod87

If you have to draw a scale for the internal structure of glass, wouldn't it be ok to put approx. 01.nm diameter for each atom (that's what it says on pp106 of the advancing physics AS textbook). I'm not sure if I'm right, but gathering from the textbook I think glass is transparent because of it's uniform amorphous structure, thus everywhere in it has the same refractive index and there are also no free electrons to scatter light photons.

riddles55, Stunt girl:

I think I'm going blind, can't believe I didn't see those pages earlier while looking through the text book. Now I bet it won't even come up in Section C tomorrow

Anyways, good luck everyone

Does ne1 have an example of measuring acceleration, can't think of why u would want 2. Anyway good luck everyone

Someone asked for standing wave formula. Method + formula here: -

E = hf - phi

where phi is the work function (i.e. the minimum energy required to release 1 electron from the material. Its usually of the order of a few eV).

hf>phi, surely?
And any excess energy becomes KE for the electron.

Yeh, its hf = 1/2mv^2 + x , x is the minimum energy needed to produce a photoelectron, actual symbol is 'phi' but dunno how to make one of them, hf is the energy of the photon, and 1/2mv^2 is the maximum kinetic energy of the photoelectron
