PPT-Chap 6: Telescopes and Detectors

The most important property of a telescope No its not its power or magnifying ability it is Its Light Gathering power So t he diameter of the mirror or lens is THE most important property. Telescopes and the group project• As an exciting new experiment each group will build their telescope• Then each of you will carry out an observing project to assess the likelihood • We Essential Questions- You should be able to answer these questions by the end of the PowerPoint.. What is the purpose of a telescope?. How do refracting telescopes work?. How do reflecting telescopes work?. Telescopes. Key Concepts. What are the regions of the electromagnetic spectrum?. What are telescopes and how do they work?. Where are most large telescopes located?. Telescopes - Key Terms. Telescope. Telescopes were first invented around the year 1600. . Galileo . Galilei was an early astronomer who first used telescopes to view objects in our solar system. . He . made many important discoveries including: the moon was covered in mountains and Jupiter had 4 large moons.. Jon Holtzman. NMSU Astronomy. Telescopes are light buckets: bigger buckets collect more light, and faint (far away) objects don’t produce much light!. Why build bigger telescopes?. In principle, bigger telescopes make sharper images:. Optical Telescopes. Ground based and on satellites. Observations are recorded using a camera instead of the human eye most times. . This is so we can separate colors into light and using times to study changes over time.. Types of Telescopes. A telescope collects light over a large area and focuses it in a . small area where it can be viewed with an eye or a camera. This can be done in 2 ways:. Refracting Telescopes. 1.
