visible light and radio waves(Both clearly shows light and also radio tide pass practically freely v Earth"s atmosphere, and also therefore are easily observed v ground-based telescopes. The only other light that can be observed through ground-based telescopes is infrared, yet it deserve to be detected only at high altitudes (such together mountaintops) and even then just in selected sections of the infrared spectrum.)
dark because X-ray irradiate does not reach Earth"s surface(Because X rays indigenous the Sun perform not with Earth"s surface, eyes the were sensitive only to X rays would have nothing come see.)
If you had only one telescope and wanted to take it both visible-light and also ultraviolet photos of stars, where must you locate your telescope?
in space(While clearly shows light can be it was observed from the ground, ultraviolet light deserve to be quickly observed only from space. Indeed, the ability of observing ultraviolet irradiate is a major advantage of the Hubble space Telescope over larger ground-based telescopes.)
Telescope time is a valuable commodity in astronomy, for this reason astronomers setup their observations carefully. Among the first steps is to choose what form of observation to make. Recall the three straightforward types of expensive observation are ________ (taking a picture of an object), _____________ (spreading an object"s light right into a spectrum), and also ________ (measuring exactly how an object"s irradiate varies through time).

You are watching: In hydrogen, the transition from level 2 to level 1 has a rest wavelength of 121.6 nm.


Type of monitoring you would do to answer this question (IMAGING, SPECTROSCOPY, or TIMING): How large is the Andromeda Galaxy?
