You may notice that not all of the rays cross at the same point. Place a convex lens in the path of the light rays (See the first figure on the answer sheet, but note that only rays going from the ray box to the convex lens are shown.)Ħ The focal length is the distance from the center of the convex lens to the point where the light rays are brought together. When the Light Blox are lined up, they produce parallel rays from the slits as shown in the figures on the answer sheet. ![]() They will represent the ray box in the diagram on the answer sheet. Part A: There are three Light Blox with different colored lights. You may need to wait until another group finishes with the equipment. Once you finish one part of the experiment, proceed to any part that is currently not in use. Each group will start on a different part of the experiment.ĥ On the lab table at which you are seated, you will find a letter, denoting the part of the experiment on which you should start. Write all your answers on the answer sheet. From what you learn, you will build a simple refracting telescope and you will analyze a simple reflecting telescope. Introduction: You will study different lenses and mirrors to determine their focal lengths. Since you ll be moving around, please move your personal items to a place so you won t forget about them. Procedure: You will be working in five stations to complete this lab. Telescopes Lab Procedure Objectives: When you have completed this lab, you will be able to: Determine how different lenses and mirrors will affect the paths of incident light rays.Ĥ Determine the properties of refracting and reflecting Telescopes. Analysis (complete Part D and E first): 14. Round all answers to one decimal place.ģ Part A (continued): Part C (continued): 4. Telescopes Answer Sheet (continued) Read the procedure to find the questions. The equation is shown below, and f denotes the focal length.Ģ Magnification=focal length of objectivefocal length of eyepiece A) What is the main purpose of a telescope ? B) What is a "focal length?" C) If a telescope has an objective lens with a focal length of 200 mm and we use an eyepiece with a focal length of 10 mm, what magnification are we using? D) If we change to a 5-mm eyepiece, does the magnification go up or down? Telescopes Answer Sheet Read the procedure to find the questions. You will be asked to calculate magnification in this lab. Answer these questions before coming to lab. ![]() Pre-Lab Assignment: In this lab, you will be investigating the parts of a telescope individually (mirrors and lenses) and then bringing them together to see how a real telescope is constructed. Any calculator is acceptable, but make sure you know the order of operations (PEMDAS). Be prepared to make calculations in today s lab. ![]() 1 Name: _ Astronomy 101 Lab: Telescopes This lab has a separate answer sheet from the procedure.
