Has anyone got any good ways of learning the Optics section from Unit 2? Having a hard time with it.

Good luck to anyone sitting the exam today.
How did people find it?

Pretty good. I made a few stupid mistakes though.
What did people get for the question about which lens to choose out of the four choices?

I went diverging in order to make the virtual image, but was unsure about the focal length, so just guessed 100mm

I put converging with focal length 150
I out diverging cause it was virtual, and 150mm.
But I got the wrong focal point because I was supposed to use -1/v as the image was virtual

How about that string 5 marker question? I got the concept wrong out I didn't find the gradient so ill probably get the equation right :frown:

Posted from TSR Mobile
For the five marker i used the formula

and got the answer to be around 6.37 x 10^something which was within the range.

I got like 6.2*10^-3 for 2 of the strings so it was in the range

Definitely my worst exam yet
For the lens one u=100mm v=-300mm(virtual so (-) ) and then used that in the equation i got 150mm and it was converging cause the focal length was positive
For the mass/length one i got that it was 6.(something)x10 to the -3 so it was in the range.
Did anybody else get these?

I got 6.25 x10-3 kgm-1 and a converging lens with focal length 150mm

Guys what did u get for the potential divider question?? And for the one about if the circuit in part b was a good representation?

Didn't like that paper. Started off easy and ended easy but all the stuff in between was like. WHAT. Haha.
