Name: ________________________ TELESCOPES: Block______ Knowledge and Understanding Complete each section in an organized and neat manner before submitting for feedback. I. RECALL: Define the following terms: Telescope Optical Telescopes Reflecting Telescopes Refractive Telescopes Radio Telescopes II. Infrared Telescopes X-Ray Telescopes Gamma Ray Telescopes Observatory Magnification DESCRIBE: Answer the following questions: How do refracting and reflecting telescopes use convex lenses and mirrors? How is laser light different from ordinary light? How are visible light, radio waves, and other forms of electromagnetic radiation different from each other? How does the size of the telescope’s main lens or mirror affect its performance? III. EXPLAIN: Complete the following using appropriate scientific language (vocabulary): Why are some telescopes placed on mountains or in orbit around the Earth? COMPARE CONTRAST: light telescopes and radio telescopes (similarities and differences) COMPARE & CONTRAST: refracting and reflecting telescopes (similarities and differences) Explain with a drawing how a reflecting telescope and a refracting telescope work. IV. EVALUATE: Answer the following questions: PREDICT: What would happen to laser light if it passed through a prism? APPLY: How could the speed of light and a laser beam be used to measure the distance between two satellites? APPLY: In order to increase the magnification of a magnifying glass, would you need to make the convex surfaces of the lens more or less curved? And why APPLY: Make a sketch of an optical tool that would use 3 mirrors to make a beam of light return to its source. Your sketch should include: The path of light waves through the tool Labels indicating the names of the parts and how they affect the light Several sentences describing one possible use of the tool ANALYZE: Why might astronomers use different types of telescopes to obtain images of the same object in space? ANALYZE: Why would it be difficult to build radio telescopes if they did not work well at low altitudes?
