Molecular radiation astronomy is a lecture as part of the radiation astronomy department course on the principles of radiation astronomy.

You are free to take this quiz based on molecular radiation astronomy at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, External links, and in the template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Suggestion: Have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

This quiz may need up to an hour to take and is equivalent to an hourly.

Enjoy learning by doing!

Quiz
{Complete the text: A white beam source focused on a sample, upon striking the sample has photons whose energy matches the { energy (i) } gaps { absorbed (i) } in order to excite the molecules of the sample, while the other photons transmit unaffected and give the sample the { complementary (i) } color.
 * type="{}"}

{True or False, The density distributions of a solid or unit of condensed matter involving more than atoms or molecules is not discrete like a spectral density but continuous. + TRUE - FALSE
 * type=""}

{Which of the following is not a studied characteristic of astrochemistry? - interstellar atoms - interaction of radiation with molecules + nucleosynthesis - organics of interstellar origin - interstellar precursors
 * type=""}

{True or False, The focus of the Submillimeter Wave Astronomy Satellite is five spectral lines from water, isotopic water, isotopic carbon dioxide, molecular oxygen, and neutral carbon. - TRUE + FALSE

{True or False, The Earth's atmosphere does not transmit green radiation between 480 and 500 nm in wavelength because of water vapor. - TRUE + FALSE
 * type=""}

{Complete the text: One of the reasons why detection of { glycine (i) } is controversial is that although { radio (i) } (and some other methods like rotational spectroscopy) are good for the identification of simple species with large dipole moments, they are less sensitive to more { complex (i) } molecules, even something relatively small like { amino acids| aas (i) }.
