The student will learn to identify the parts, functions, magnification, and light gathering power of the classroom refracting telescopes, and learn how to operate the classroom telescopes.
Procedure Sketch the refracting telescope.
Knobs Lock Levers Draw a schematic of the telescope and show the path that light takes, from the objective lens to your eye. In words, summarize how we determine the magnification of a telescope. That is, the larger telescope is 20 times as large, but has 400 times the light gathering power. The 8-meter Keck telescope in Hawaii is one of the largest in the world.
