Ast 220 Test 2 Exam Questions and Answers
Verified by Experts
what 3 things do scientists do with telescopes? take pictures, collect spectra, look at
variations in the intensity
why is it important to have high positions when using a telescope? less atmophere to pass
through
why is it important to have dry conditions when using a telescope? no clouds to block
your view
why is it important for it to be dark when using a telescope? no light pollution
what can happen with too much moisture with a telescope? the atmosphere can interfere
and cause the image to distort
visible light telescopes ground
radio wave telescopes ground
gamma ray telescopes in/out of the atmosphere
, x-ray telescopes in/out of the atmosphere
ultraviolet telescopes in/out of the atmosphere
infrared telescopes in/out of the atmosphere
which wave is the easiest to collect with interferometry radiowaves
Interferometry process that links separate telescopes so they act as one telescope,
producing more detailed images as the distance between them increases.
emitted light light that is spontaneously given off
absorbed light light captured by matter
transmitted light light that passes through the object
reflected or scattered light when radiant energy (such as light) is "bounced off" an object,
such as a solid colored surface
photon a single particle of light
