Here are my results, and i am trying to show that my results are accurate and also trying to show 1/f = 1/Di + 1/Do from my graphs, sorry for being such an idiot I am a gcse physics student and i have no idea what I am doing, one thing for sure i won't be picking it for A levels :P
my y intercept is 0.0945 and my x intercept is also 0.0945 if that helps. Also the ligh source was a small lightbulb. We changed the distance of the lightbulb and took a reading of Di. I am not giving a lot of detail as it might go down as cheating
Hi,
Well I did it Di vs Do and it is a straight line from the top left going down to the bottom right. I have a gradient of -1 and from my understanding f= gradient so my f is -1. 1/-1 is -1 and when i add my Di and Do i don't get -1 instead i get 0.09 ... which is positive not negative. So what...
Well at school we are doing an experiment to find out the factors which affect the distance between the lens and the image.
Well I did the convex lens experiement and from my results i plotted a graph which is y vs x
The distance between the lightbulb and lens is x and the distance between...
