Spectral Analysis Quiz - Level 1
Spectral Analysis Quiz
One example of a spectrum that most people have seen is:
[A] the Northern Lights
[B] the Big Dipper
[C] a rainbow
[D] an erupting volcano
In order to make a spectrograph, you must
[A] separate light into parts, by energy
[B] observe light from space
[C] have a computer
[C] use graph paper
Because each element has a unique spectrum, we can use spectra from objects such as stars to tell us
[A] how old they are
[B] how far away they are
[C] what the star is made of
[D] how big they are
X-ray spectra are especially useful because
[A] X-ray lines come from atoms with only a few electrons
[B] X-ray lines come from gas at high temperatures found in extremes such as the solar corona, supernova remnants, and clusters of galaxies
[C] it can be simpler to draw conclusions, about elemental abundances, for example, from X-ray lines
[D] all of the above
