Place check marks on Principal Rays, Focal Points, Virtual Image, and Labels. Keep default values for Curvature Radius R = 80 cm (R1= 80 cm and R2 = -80 cm). Set Refractive Index of lens n = 1.5 and Diameter of Lens to max D = 120 cm. Place cursor on pencil (object on left side) and move up till eraser tough the Optical Axis (central line). Test and understand all functional tools on screen. You must practice guring out what is the best way to complete the measurement.
