Aww I didnt know there was such a thing! How would you distinguish between that and a gridless quadrat? I wonder would they allow both as you wouldnt be able to tell as a diagram
I got the same answers as you, give or take. I have a question, which way were you meant to set the block on the page? If I remember correctly, the diagram showed the block to be resting on the small side.
Position of object was at 100cm point, position of lens was at 50cm point so u was 50cm. Distance from 0cm mark to screen was like 21cm or something so v would be 29cm. My table had 4 extra columns for u, v, 1/u and 1/v with u + v in cm and 1/u + 1/v in cm-1
