At what place along the rainbow of visible light does each pattern of dark lines show up with a spectrometer?
A specific place.
What information does each pattern of dark lines provide when observed with a spectrometer?
Information about the specific place along the rainbow of visible light.
What is the phenomenon that occurs as we get further out into space and observe spectral lines?
The spectral lines appear shifted to the red end of the spectrum.
What is the instrument used to observe the phenomenon of spectral lines shifting to the red end of the spectrum?
Spectrometer.
What information can be obtained from observing the spectral lines with a spectrometer?
The information about the composition, temperature, and velocity of the observed object.
What causes the spectral lines to shift to the red end of the spectrum as we get further out into space?
The phenomenon is caused by the Doppler effect, where light waves are stretched out as their source moves away from the observer.
What is the significance of observing spectral lines in astronomy?
Observing spectral lines helps astronomers determine the composition, temperature, and motion of celestial objects.
