Astronomy A Beginners Guide To The Universe 7th Edition By Chaisson Test Bank With Verified Questions And Answers Telescopes: The Tools of Astronomy 1) The simplest reflector telescope design is the prime focus reflector. Answer: TRUE Diff: 1 Section Ref.: 3.1 2) Galileo is credited with designing the first reflector telescope. Answer: FALSE Diff: 1 Section Ref.: 3.1 3) Chromatic aberration affects reflector telescopes. Answer: FALSE Diff: 1 Section Ref.: 3.1 4) All optical telescopes will bring the light from a star to a focus. Answer: TRUE Diff: 1 Section Ref.: 3.1 5) A telescope design that uses a lens and no mirrors is a refractor. Answer: TRUE Diff: 1 Section Ref.: 3.1 6) CCD detectors gather light 10-20 times faster than the most sensitive photographic film. Answer: TRUE Diff: 1 Section Ref.: 3.1 7) A Newtonian reflector needs no secondary mirror. Answer: FALSE Diff: 2 Section Ref.: 3.1 8) The Hubble Space Telescope gives us its best resolution with X-rays. Answer: FALSE Diff: 2 Section Ref.: 3.1 9) The Cassegrain reflector needs a primary concave main mirror and a smaller, convex secondary mirror to reflect light back through a hole in the primary. Answer: TRUE Diff: 2 Section Ref.: 3.1 10) Photography with film is still the preferred way of capturing fine detail in the faintest, most distant galaxies. Answer: FALSE Diff: 2 Section Ref.: 3.1 11) The light-gathering ability of a telescope is most dependent on the diameter of its primary objective. Answer: TRUE Diff: 1 Section Ref.: 3.2 12) Mt. Palomar’s 200″ Hale telescope is the largest reflector now in service. Answer: FALSE Diff: 2 Section Ref.: 3.2 13) A telescope with an 8-inch mirror will collect twice as much light as one with a 4-inch mirror. Answer: FALSE Diff: 3 Section Ref.: 3.2 14) The 400″ Keck reflector can see objects 100 times fainter than the 40″ Yerkes lens. Answer: TRUE Diff: 3 Section Ref.: 3.2 15) Radio telescopes have poorer angular resolution than optical telescopes because radio waves have a much longer wavelength than optical waves. Answer: TRUE Diff: 1 Section Ref.: 3.2, 3.4
