Anybody??

My results are all ****ty, say for instance I wanted to make up some results. I'm using an LED with a green and red light, a lens, a white block (improvised as a screen to project the image -red or green light-) and a metre ruler. What sort of results do you think I would get or see?

Well, using a suitable lens I had to take measurements over a range of object and image distances to help me plot the graph. I've got some results, but I don't know if they're correct or suitable. I'm not sure what you mean in the first half of your post.

"To use a graphical approach to determine whether there is a difference between the focal length of a lens when used with red and green light." What would I expect to see? What sort of results do you think I will get? What would be the variable? I need to use the equation 1/u +...

Anybody please? Feel free to help, my deadline is tomorrow :(

Can you elaborate? I'm really not getting this :redface:

Please? :confused:
