greatly apprecaited :P i think i saw that in excel?

thx:P

well the books describe four distince emission lines observable in the spectrum when observed with a spectrophotometer....these invariably helped bohr develop his model because he was looking for that extra 'something' to explain why electrons dont just fall into the nucleus from constant...

ahha no even then the discovery of the photoelectric effect did not lead to the discovery of transistors as such, but was rather an application brought about through alternating layers of positive and negative type semiconductors? wont u agree with me here? to illustrate my point, lets...

ahha i know what this is....cos its my namesake lol...haha nar jkjk anyways the syllabus requires students to describe one way in which emitted radiation may be observed in the laboratory...other apparatus include photographic film, geiger-muller counters and scintillation cameras...although i...

yeah it has the diagram but i dont understand it!! wahhhhhhh :( also why is it 2dsintheta?

no because u can get employed by top aero defence companies

this is basically an offshoot from the superconductor thread i posted earlier, but can someone please explain to me the essence of the Braggs' X-ray diffraction experiment and how they derived the formula n,\=dsintheta thanks alot

ahh okay...thanks alot :P

hey what exactly does the MLitt postgrad degree entail?

where can i obtain a form for registration of interest? i have searched through their site but to no avail./.......

no way man! this is a standard term :) edit: i think this term is used in relation to some gases in the atmosphere which are present in minute amounts...also in roland smith in relation to the greatness of AAS in monitoring ions in our waterways

it is arguable the extent to which one can maintain textual integrity in the application of a reading...for as Marx mentioned in his famed manifasto...Ideologies are subject to socio-economic forces and to think otherwise would be deceiving ourselves with a 'false consciousness'... anyhows...

i onli know ammonuim tetrammine...which is an 'electric blue' complex ion... however i dont think you should worry yourself too much with these types of ions...only those which are relevant to the syllabus...

ahhh yep you're right.... i googled it :P http://www.sunderland.ac.uk/~hs0dad/qm/testv2a/2_concen.htm

its funny in its own way though :P click here

hmmm i think its where u have to dilute a substance by a suitable factor, why you would want to im not too sure, but one example i can think of from the top of maH Head is where you are doing a titration on ethanoic acid (vinegar)...so you would have to apply a suitable dilution factor before...

parts per billion... so 1 ppm (parts per million) is equivalent to 1000 ppb :)

dont let the fact that the book is very ols, and not in colour turn you off...have a serious look at it and try and understand the concepts involved

u also should mention john that heisenbergs undertainty principle is further theoretical evidence for the DeBroglie theory of matter WAVES since this theory talks about the probabilities of electrons being in a particular location at any given time~
