An object O stands at x = 0 on the x-axis. Lenses 1 and 2 are places at x = 12 cm and x = 18 cm on the x-axis respectively. The radii of curvature of the two surfaces of Lens 1 and Lens 2 are given in Figure 2. The index of refraction for the two lenses is 1.52. r=8 cm r=10 cm r=2cm flat Lens 1 Lens 2 Figure 22 (a) Find the focal lengths of lens 1...
