Apparently it was a V-I graph not an I-V graph so it wouldn't have looked like A if that's the case


Wait do you mean there was a grapgh of diodes but one showed V/I and other showed I/V

What did everyone put for effects on % uncertainty. I put increase % u in area but decrease in extension because greater extension so more measurable and thus less % uncertainty

No some guy commented earlier that it wasn't an I-V graph, but most people would have assumed so given the rush to finish, but a V-I graph. But I'm not too sure about this

Im pretty sure it was a regular I-V so A
Im guessing the flipped one might have been used to catch out people who thought its reversed because of the resistor

got the same

I put the uncertainity increases on measuring diameter using calliper if it decreased and i couldnt think of second one so i put systematic error eill increase as accuracy is decreased :/

Was that the SECOND smallest gap by any chance


surely it was e1 to ground state because that was the only one larger in energy difference

50 for an A maybe?


Noooo, i reckon a lot lower. Even my physics teacher thinks it'll be like... 65% for an A
Original post by 83457
did you round it to 10 or keep it as 3sf?


I kept my answer to 3sf as it didnt state in the question any marks would be rewarded for the correct sif figs

so 45 for an A what about 90 ums?

The put the one that the biggest gap (ground state to the one above the ground state), I cant remember the numbers am I right?


I put that as an energy difference bigger than the visible light means a higher frequency than visible light

For the mcq with K0 did anyone put B
This is what I remember...
114W for power...
2.11*10^whatever for ym in MCQ
4 resistors
10,000microvolts(or volts unsure)
Y=mx+c so line graph was better for section A question
Lamda/4 for alpha in MCQ
f stayed the same in MCQ
The rest is a blur....👀
I got 2f for the frequency mutiple choice

did anyone get f/square root 2 for the a mcq

I think it asked "What is the maximum amount of components you can add without reaching maximum power" or something. So I imagine you have to round down or you will go over the max power.


Ah, I see, I think I read it wrong then since I would usually round down unless something said otherwise - my bad.
what did everyone get for the diameter of the wire (the question that contained a zero error)
What was the last multiple choice answer, I had no time just but B down somet like 0.7??? But what was the real answer?
You had to realise that UV has a higher frequency therefore a higher energy therefore the biggest gap
