Hello. I have a very simple question that I need answered for my science project. I am doing a project on the effect of the convexity of the lens on the intensity of converged light. (Lux?) I am using a class set which I haven't been able to get my hands on yet, but we are expected to be completing introductory papers and such. I need a basic idea of the relationship between convexity of lens and intensity of converged light so I can work out some of the basics for my papers. Thanks!
