Nick Orozco Section 5 24 March 2008 Lab Partner: Colin Smolinsky Chapter 10: Optics and the Telescope Purpose: This lab is only the first in a two-part series. In this first installment, the purpose was to examine the properties of a single lens system. We will learn to use two different techniques for measuring the focal lengths of the eyepiece and the objective. The first technique is known as the simple imaging method and the second method is known as the auto-collimation technique. We will learn more about the imaging properties of a single lens system by using these two techniques. In the second installment of this lab, we will compare measurements made using the single lens system with the measurements made

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....
