Question
Pad * 43% 12:00 PM instructure-uploads,s3.amazonaws.com 52 Telescopes and Earth's Atmosphere 1) Which, if any, of the different wavelengths of light (electromagnetic radiation) shown in the image on the previous page are able to completely penetrate Earth's atmosphere and reach the surface? 2) Which, if any, of the different wavelengths of light (electromagnetic radiation) shown in the image on the previous page only partially penetrate Earth's atmosphere and reach the surface? 3) Which, if any, of the different wavelengths of light (electromagnetic radiation) shown in the image on the previous page are completely absorbed in Earth's atmosphere and never reach the surface? 4) Federal funding agencies must form committees to decide which telescope projects will receive funds for construction. When deciding which projects will be funded, the committees must consider that certain wavelengths of light are blocked from reaching Earth's surface by the atmosphere how efficiently telescopes work at different wavelengths, and that telescopes in space are much more expensive to construct than Earth-based telescopes Use these three criteria when you consider each pairing of telescope proposals listed below (a-d). State which proposal out of each pair you would choose to fund. Explain the reasoning behind your decision for each pair. a) Which of the two proposals described below would you choose to fund? Project Delta A gamma ray wavelength telescope, located in Antarctica, which will be used to look for evidence to indicate the presence of a black hole Project Theta A visible wavelength telescope, located on a university campus, which will be used in the search for planets outside the solar system. Explain your reasoning © 2013 Pearson Education, Inc. LECTURE-TUTORIALS FOR INTRODUCTORY ASTRONOMY THIRD EDITIONExplanation / Answer
1. The visible light portion largely passes the Earth's atmosphere. This is due to the atmosphere's ability to absorb specific wavelength and frequency radiation while allowing specific wavelength and frequency radiation to pass which is called transmissivity.
