Astronomy Lab Test 2

Take this test if you know anything about Astronomy. See if you can master it. This test is about spectroscopy and some other stuff. Let's see how well you do.

Are you an astronomy genius? Take this test to find out. There are 30 questions in all. How many will you answer correctly?

  1. Compared with a spectrum from a ground-based observation, the spectrum of a star observed from above Earth's atmosphere would show.
  2. The visible spectrum of sunlight reflected from Saturn's cold moon Titan would be expected to be.
  3. Compared with a star having many blue absorption lines, a star with many red and blue absorption lines must be.
  4. An atom that has been ionized.
  5. Compared with a complex atom like neon, a simple atom such as hydrogen has.
  6. Compared with cooler stars, the hottest stars have absorption lines that are.
  7. Compared with slowly rotating stars, the fastest spinning stars have absorption lines that are.
  8. Astronomers analyze starlight to determine a star's.
  9. An instrument used to view a light source so that it is split into its component colors.
  10. The study of the way in which atoms absorb and emit electromagnetic radiation. This also allows astronomers to determine the chemical composition of stars.
  11. A bright line in a specific location of the spectrum of radiating material, corresponding to emission of light at a certain frequency.
  12. An elementary particle with a negative electric charge.
  13. Matter made up of one particular atom.
  14. The pattern of spectral emission lines produced by an element.
  15. Three rules governing the formation of different types of spectra.
  16. Roughly the same mass as a proton, but which is electrically neutral.
  17. Dense, central region of an atom, containing both protons and neutrons, and orbited by one or more electrons.
  18. State of an atom or molecule that has lost one or more of its electrons.
  19. Individual packet of electromagnetic energy that makes up electromagnetic radiation.
  20. Emission of an electron from a surface when a photon of electromagnetic radiation is absorbed.
  21. A particle carrying a positive electric charge a component of all atomic nuclei.
  22. Spectrum in which the radiation is distributed over all frequencies, not just a few specific ranges.
  23. Dark line in an otherwise continuous bright spectrum, where light within one narrow frequency range has been removed.
  24. Dark line in an otherwise continuous bright spectrum, where light within one narrow frequency range has been removed.
  25. Building block of matter, composed of protons and neutrons in the nucleus surrounded by electrons.
  26. State of an atom when one of its electrons is in a higher energy orbital than the ground state.
  27. The lowest energy state that an electron can have within an atom.
  28. The fact that light and matter on small scales behave in a discontinuous manner, and manifest themselves in the form of tiny "packets" of energy, called quanta.
  29. A tightly bound collection of atoms held together by the atom's electromagnetic fields.
  30. If a continuous spectrum passes through a cool gas, atoms of the gas will absorb the same frequencies they emit; this is called_________.
