Telescopes can be made with either lenses or mirrors. Using what you know about lenses and mirrors, you can think about ways to make small things that are far away look larger. Two members of the Physics Hall of Fame made important contributions to science by inventing telescope designs. Galileo designed a telescope that used lenses, Newton designed the first telescope that used mirrors. Compare and contrast the Newtonian and Galilean telescope designs. Explain the operation of each using your knowledge of optics. Illustrate the operation of each device using ray diagrams. Describe the advantages and disadvantages of each type. Criteria and Checklist: As you complete your assignment, please review the checklist below to ensure that you have included all needed items. Your assignment should include all of the criteria listed below to receive full credit. Included? Item 1. Describes Newtonian and Galilean telescope designs in detail. 2. Compares and contrasts the design, functions, advantages, and disadvantages of each telescope. 3. Applies knowledge of lenses and or mirrors to explain how the telescope works. Explanation includes a ray diagram with at least two rays drawn from the object to the image. 4. Presents information clearly to audience.
