well, now I can talk about physics paper 6 without breaking any rule (it's been over 24 hs since I sit for it)... the question is how do you measure the thinkness of a lens using two wooden blocks??

I answered that you need to measure the thikness of both wooden blocks, and then place them block-lens-block; the blocks parallel to each other and touching the lens by each side. Then measure the thickenss of all the three things together (block-lens-block) and to this measurement substract the initial thickness of both blocks.

Is this right??
Sorry if the description is not very clear; but I draw a diagram in the exam (that's what the question asked for) .

Thanks!

I dont remember for sure but i remember that when i used it to find the focal length, the focal length was like 11-12 cm.. somthing like that, oh and i remember for sure that the length of the lens was 6.5cm

got 6.5cm for the length
and 0.85 for the thickness
i think i got 15cm for the first focal length
and 11.6? or rather for the second focal length

paper 6 was damn easy. we had to plot the graph of T2 to x (cm)

i got the graph as an exact straight line, and thus concluded that they are inversely proportional.
