It was snow, there were higher levels of UV detected because the snow reflects more back into the dummy's eyes. . . I think.

Crap! I lost one mark there then!! *******

I drew the analogue graph as an alternating current graph, but I drew the digital graph as bar chart graph (as in I drew it properly with spaces between bars). Would I lose 1 mark then for drawing the incorrect analogue graph?

But if it reflects off the surface then it I'd more likely to hit the person so I put snow. What was the independent variable. Was it the dummy changing sides or he surface ?

what topics came up.. someone make an unofficial markscheme?

I didn't think you had to draw graphs. Just a random squiggly line for analogue to show variation, and a Rectangle up and down line for digital to show 0 and 1 positions.

Or am I wrong?

Probably just one. Did you need to add labels? I did just to make sure.

Independent variable was surface, I guess, it seemed the point of the investigation to find out which surface reflected more. And I'm pretty sure it was snow. P.S nice phone

That's what I thought!

Yeh I did surface and snow. And thanks though I am not sure why it needs to tell you my phone name haha

Yeah I meant in the box... it didn't have to be a full graph with axes such and such - just a normal line or rough sketch of what it is...

[ClarkyC...]

To clarify the analogue was just a graph with varying amplitude and the digital was straight same height like lines with discrete values

What were the topics in the exam???? Well???

[ClarkyC...]

A lot on radiation and communications, some on biogas which is a bit weird lol

Lol Thats it? what kind of questions?

[ClarkyC...]

Is this for a mark scheme or something?

Yeah

[R.P.Everything.]

Anyone get cobalt 60 as the material to irradiate food with?

[MichelleQ]

Me Please remind of all the questions and topics?

[R.P.Everything.]

Also, did everyone get UVC as the UV radiation that doesn't harm human eyes and skin?

I DID! because gamma can pass through packaging and it had a fairly long halflife and it was the least ionising but im not too sure about the ionising part :s

Omfg after looking at this i failed
