Semi worked solutions for Light, Electric power and Sound

I'm bending over for you now "whatlol" you are messiah.. note, please don't take this bending as sexual.

for the n=4 to n=2 isnt there 2 arrows
cause they said something abbout 2... so n=4 to n=3 then n=3 to n=2 ?

Nah they said a transition between two energy levels so from one energy level to another I'm pretty sure.

[Whatlol]

 " A photon of wavelength 478nm is emitted from an excited hydrogen atom, The emerging photon is caused by a trasnition between two energy states. Draw an arrow on Figure 6 that shows this transition from the initial to the final energy state"
so what blackhitman said.

omg so i dont get a mark or 2 T___________T WAHHHHHHHHHHHHHHHHHHHHHHHHH
so far 2+2+2+2+2=10 OMO SO MANY MARKS GONE


damn my shit english understanding

that makes me feel like crap...do i get 1 mark atleast =D???

hmm not sure to be honest i dont really know what they will do, unfortunately i dont think so

THANKS TO WHATLOL'S UBER GOOD SOLUTIONS I HAVE FOUND OUT THAT I LOST A MINIMUM 14 marks...do i still get an A ? maybe? ..no chance?

its possible, say A+ cut off is about 83 - 84 you may get an A

The circuit question?? does it matter how we drew it    i drew it in series but not a digonal :|

i honestly dont know i got it wrong. i assume if you did it in series it should be ok

How did you draw it then?
Because you can't just leave the end of the second element unattached (assuming you just drew a vertical line connecting the two). The circuit would not be complete.

[waack]

what lol did u draw a vertical line down the left side? cause i did bloody rushing costs ya

no, id rather not discuss what i did because it lost me 2 marks )=

[Elnino_Gerrard]

I KNOW OK i dint think of diagonal line thattime but its still series??

[waack]

thats parallel
