Module 9: Optics Authentic Assessment 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
