I am trying to figure out where is the focal point and where is the image. I read some information online about the point where you see the image is the focal point, but however, my supervisor mentioned the point where you see the image is on "point 2" on the drawing. But as I remembered from school, the "point one" is where the retina is in order to have a good vision in our eyes.
The main purpose I am asking this because I want to get as much light as possible to a small area, and me and him were trying to figure out which point has the maximum light. I managed to obtain a focused image on a sheet of paper when doing the experiment (I believe that's point 1). Please help, Thanks a lot!!
Basically, could you tell me which point has the maximum intensity of light and if possible, point one or two is the image is. Thanks
