1. It was easier than jan thats 4 sure...i shud have wrked a lil harda me thinks ..how did u guys find it...

firstly - sorry for pissing you off about the light intensity thingy

and the second bit i found weird was teh spider weeb thingy - i got 16.3 Hz or something ike that

what grade do you think you got?

pk
3. I Dnt Think I Did Betta Than Jan

why what did you get in janruary?
5. got 70/90

i got that aswell me thinkz
7. i did jan 05 2 days ago and found it easy [different people good at different things]. Todays paper seemed to be easy stuff made harder instead of the good ole harder topics, which kinda pissed me off as i didn't really revise them. It was a lil confusing in what they wanted to know at times, i think i got at least a low A hopefully [72/90]. For droplets thing i got 16.3 Hz

2 x [half wavelgnth] = 1 wavelength x 0.25, then i used v = f.lambda.

YES - but i didn't use 2x1/2 wvelength - i just used peak to peak and said it was 2.4cmx0.25 and did v=λf

hope everyone else gets that too - was the only question i wasn't completly sure how to do - just blabbed that!

lol
9. what grade boundary you think phy4 will be?

Peeps in my college said phy4 was easy [the brainy people] and the C/D peeps said it was really hard comparing to other papers. [I thought it was quite confusing, it's just too hard to predict if i got them questions right or not].

And where was the damn absorption specturm/emission spectrum

It was easier than jan so the boundary is gonna be a lil hi methinks
11. anyone know what the grade boundaries are in terms of raw marks for the PHY 6 as a %age?

i heard that last sumemrs one was 66% - is this true?

phil
12. i found january paper easier, how did everyone else find it? I think it'll be about the same give or take 1 ums.

Yeah iy was 66%, but it's usually 68%-74%
14. did u have to minus the displacement of the standing wave from that of the one to get the displacement of the other progressive wave ????
15. Hmm... about filling spaces question ... something like 100m and 10^-6m ... what did you do?
16. 100m i put UHF...10^-6 is microwaves isnt it???

10^-6m I think is IR (microwave is about 1cm ??)
18. (Original post by nas7232)

i figured out that i need 50% to get an A overall in my physics (roughly)

woo hoo!

just hope my calculations are correct, - was based on teh assumption that i get 85% in phy 4 and 90% in phy 5)

phil
19. and what emits light of wavelength 10^-6m ??
20. (Original post by BCHL85)
10^-6m I think is IR (microwave is about 1cm ??)
o yea...i put IR ...soz got mized up
