[edit] wave properties/unifying concepts
I had left these two "modules" out, since despite having seperate exams, wave properties is covered under electrons and photons as far as the specification is concerned. unifying concepts also has a seperate exam, but according to the specification, it is nothing but material covered in the other modules. I will leave those sections there if you feel that enough original content can be added to them. --Krackpipe 22:19, 25 August 2005 (UTC)
Wave properties - this is waves, waves, waves. My recollection of this was that it was almost all done in respect to water surface waves, although I remember reflection and diffraction of light waves, especially Snell's law, critical angle, and application to fibre optics. And sound, vibration in strings, organ pipes. The dual nature of light is covered in Electrons and Photons.
Unifying topics I think would cover how the fundamental principles of physics apply throughout the field - conservation of energy; conservation principles in general; approximate correctness of Newtonian physics at everyday scales of speed, mass, and size; relativistic physics for big and fast; quantum mechanics for the very small.
Ideally each of these fundamental principles would be illustrated by at least two examples of application in different contexts. For instance, how the trajectory of an electron in a television tube has to be calculated relativistically due to the high velocity, yet the rays that it produces on hitting the phosphor screen can be analyzed using classical optics. This demonstrates how sometimes Newtonian physics is a close enough approximation (watching TV), but not always (designing the TV tube).
Those fundamental principles would, of course, already have been covered in their respective sections. --Wrolf 17:28, 26 August 2005 (UTC)
ok, lets keep them, i dont really have any big problems with that. if they dont develop more than a few lines or so, then we could merge them with some of the other sections.--Krackpipe 20:26, 26 August 2005 (UTC)
I'm adding in the Wave Properties section, since as far as I can tell, not everything here is covered in other sections, and I think that sticking to the format of the specification will make life easier for both readers and writers. --Justdig 01:54, 17 April 2006 (UTC)
[edit] Orphaned page
G'day, A-level Physics/Edexcel (Salters Horners) seems to be lost - nothing links to it. Could somebody please integrate this back into the book, or alternatively tag it for deletion? thanks, Webaware talk 14:09, 17 March 2008 (UTC)
