  1. Fix Astronomy Chapter 6

  2. Question 1 The Hubble Space Telescope has made significant contributions to astronomy, including spotting storms in the atmospheres of our outer planets, collecting images of forming planetary systems, verifying of the existence of super massive black holes in the centers of some galaxies, and direct observation of impacts on Jupiter. A. True B. False

  3. Question 2 Today the largest visible light-reflecting telescopes are the twin 10 meter Keck machines located near the top of Mauna Kea on the Big Island of Hawaii. A. True B. False

  4. Question 3 Light from a distant object passes through the lenses of a typical reflecting telescope. A. True B. False

  5. Question 4 Astronomers typically use their eyes to look directly at objects in the sky at the prime focus of the largest telescopes. A. True B. False

  6. Question 5 The small Schmidt telescope on Palomar Mountain, California is the largest refractor in the world. A. True B. False

  7. Question 6 Which of the following statements best describes the two principle advantages of telescopes over the unaided eye? A. Telescopes can collect far less light with better resolution. B. Telescopes can collect far more light with better resolution. C. Telescopes can collect more light and are not affected by twinkling. D. Telescopes can collect less light with poorer resolution. E. Telescopes are not as good as your eyes.

  8. Question 7 A student purchases a 4-inch reflecting telescope at the mall. What is the light gathering power of the student's telescope compared to the 2-inch telescope owned by the class instructor? Assume both telescopes have circular optics. A. 4 times greater B. 2 times less C. 4 times less D. 2 times greater E. equal

  9. Question 8 _________________, ___________________, __________________ and the Coude are four types of focus designs for a standard reflecting telescope. A. Direct, Kelper, Cassegrain B. Cassegrain, Newtonian, Parabolic C. Direct, Yerkes, Palomar D. Direct, Newtonian, Cassegrain E. Newtonian, Meade, Celestron

  10. Question 9 The speed of light in a vacuum is A. greatest for red light due to its long wavelength. B. greatest for blue light due to its higher photon energy. C. greatest for only the shortest wavelength photons. D. the same for all wavelengths of light. E. varies as a function of wavelength squared.

  11. Question 10 Visible light, ultraviolet radiation, infrared radiation, radio waves, and microwaves are all examples of A. sound or sonic waves. B. radioactivity. C. gravitational waves. D. electromagnetic waves.

  12. Question 11 The Doppler effect (also know as red shift and blue shift) causes the wavelength of light to be shifted by the motion of the source of the light. If a source of light is moving away from Earth, the wavelength of that light will be shifted toward A. shorter wavelengths (blue shift). B. longer wavelengths (red shift). C. wavelength is constant, no shift.

  13. Question 12 How many 4 meter telescopes would be required to match the light gathering power of a 15 meter telescope? A. 2 B. 6 C. 14 D. 20

  14. Question 13 Telescope A has a mirror that is 10 times larger than the mirror of telescope B. Telescope A can resolve an angle as small as 0.1 seconds of arc. What is the smallest angle that can be resolved by telescope B? A. 10 seconds of arc B. 1 second of arc C. 0.1 second of arc D. 0.01 seconds of arc

  15. Question 14 Suppose you want to determine if there is any methane gas on a newly discovered planet. You need to equip your telescope with a A. CCD. B. photographic plate holder. C. spectrometer. D. space probe - can't determine anything about gases without traveling there.
