    Experiment 9- Thin Lenses Introduction Experiment 9 introduced us to the concept of thin lenses. We were asked to determine the focal lengths of two converging lenses and one diverging lens. The following equations were used to calculate the focal lengths: 1/p + 1/q = 1/f where p is equal to the distance of the object from the lens and q is equal to the image length from the lens‚ and f is the focal point and 1/converging F+ 1/diverging F = 1/combined. The focal point is positive for converging
