Unformatted text preview: in a two-lens system. 10.2.1 Simple Measurement of a Lens’s Focal Length 1. Focal length of eyepiece: ~ 3 cm 2. Focal length of eyepiece objective: ~ 52 cm 10.2.2 Using an Auto-Collimation Technique to Measure the Focal Length of the Objective Lens 1. Focal Length = 42 cm 2. D mirror = 62 cm 3. The image is inverted 10.2.3 Magnification in a Single-Lens System 1. D image = 84 cm 2. D object = 88 cm 3. H imag e = 6 cm 4. H object = 6.5 cm 5. M = -0.955 (ratio of image distance / object distance) 6. M = -0.923 (ratio of image height / object height) Post-Lab Questions 1. There could be a multitude of sources of error including the following:- Poor condition and positioning of the lenses and the mirror (Systematic)- Variations in the power and intensity of the light source used (Systematic) 2....
