V Discuss The Newtonian telescope is also known as the poor man's telescope. It is a reflecting telescope that was invented by Sir Isaac Newton in 1689. It consists of a large tube open at one end with a large converging mirror at the opposite end. Light from a distant object enters the tube and is reflected from the surface of the large, concave, primary mirror. The reflected light is then incident on a small, flat, secondary mirror that redirects the light into an eyepiece for viewing. The geometric location of the secondary mirror is related to the curvature of the primary mirror. W Module 5: Lesson 3 Assignment Remember to submit your answer to D 1 to your teacher as part of your Module 5: Lesson 3 Assignment. D 1. Determine where, exactly, the secondaryr mirror should be placed so that the telescope produces a clear image of the distant object. Use a ray diagram to answer this question, and design an experiment to determine the focal length of the large, primary.r mirror. Your design should include the problem, prediction, materials, procedure, and analysis required to answer the problem.
