PHY1H (OLD SPEC) Unit 1 AQA GCSE

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 ?

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?

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

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...

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