I estimated the wavelength of ultraviolet to be about 670nm and used delatE=hc/lamda to find an estimate for the difference in eV. Pretty sure it turned out to be E1 to E2


Ultraviolet waves have way more energy than photons so i chose the one with the biggest gap which I think was E2-E0 (if that was an option, which i cannot remember too well)
83000 anyone
The graph question about changing velocity time graph to accelration graph .... I thought for this one that since the gradient of velocity time graph was curve, it meaning that that it was decreasing accelration so i picked up graph that was showing accelration being curved and reaching zero eventually :smile:

What did you get for the IV graph

What did you get for the IV graph


The one with circuit shown, dioide and resisitor?.?

What do you think 56/69 would be which is 81%

I remember guessing the second largest 83... option. Was there a choice greater than 83000? If 83000 was the largest then I lost another mark :/

Yep did you get A

Yeah you had to work out time using suvat and then plug it into f=mv/t
Isn't the falling object graph the one with constant acceleration D?

Yep did you get A


To be honest i am not sure, i guessed that one and by accident put the one that didnt show anything ... I only had 10 second to think for that

What did everyone get for the IV graph with the resistor and diode and what do you reckon 56/69 would be

A the normal one i thought

WHere it increases from an x intercept linearly right? What do you reckon you got, Im so scared about boundaries now :frown:

What did everyone got for explaining why one graogh is better than other or something like? All i put is that straight is better because it shows linear relationship which means that they will be less error on the value found either using gradient or y intercept etc hence this will make it more accurate ... I dont think if this is rught though

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

Yeah I pput something like that saying how you could use y=mx+c
