OCR Physics B! 22nd may!

So the top was 4 and the bottom was 0.01?

No, the top was 0.4; and btw "relative probability" just means that when you add up all the separate probabilities it doesn't have to come to 1.

The relevant lines of the table were:

$\begin{array}{r|l|c} Amp & Prob & Int. \\ \hline ? & 0.16 & 32 \\ 1 & ? & 2 \end{array}$

And since $I = kA^2$ and $P = A^2$ finding the two missing boxes should have been quite straight forward.

However much revision I do, there's no way I could have done better than I did today, and I don't think I did too well. I've been constantly revising for so long for this exam, yet nothing I revised helped. I was constantly having to try to think outside the box, stuff which simply wasn't included in the syllabus. They deliberately try to trick you don't they, they just love it.

First one was poor for me, second was better but not by much. I'm really annoyed that I won't get rewarded for the work I put in. Dam you OCR

Did anyone answer that question that said something about 0.75 the increasing factor every 200 virations. And we were given the frequency and had to show that something is 5% more than blahhh blahhh
My teacher said that was something beyound our level (AS) and they shouldn't have included that becuase exponential was not part of our syllabus
