Homework Help: Converging lenses and focal point

  1. Sep 5, 2005 #1
    Hi,
    I'm new here! I had a Physics question for you guys. I graduated from college about a year, but I'm studying for the MCAT so I'm revisiting Physics, lol. I'm on the light/optics/lenses chapter in my review book, and it states:
    Now that can't be right, can it? By definition, converging lenses produce the convergence of rays towards the lens' central axis and the focal point is where all the converging rays that have passed through the lens come together. So then the focal point is in front of the lens and is positive. Am I missing something? I don't have my old physics book with me to check it more in depth so I appreciate any help. Thanks, and I hope I'm not too confusing.
