The spectral lines from distant galaxies do not match those on Earth because of the Doppler effect, cosmic expansion, and differences in elements present in the galaxies. These factors cause the observed spectral lines to be shifted or altered compared to what we see on Earth.
Quasars have all kinds of spectral lines namely more energetic ones which makes them the brightest objects in the night sky.
Elements have several spectral lines and although some lines may be the same between different elements most lines are not and the whole spectrum for each element is indeed unique.
Spectral interference is more common in atomic emission spectroscopy due to overlapping spectral lines.
No, the spectral lines of two different elements are unique and vary based on the electron configuration and energy levels of each element. This is how scientists can identify and differentiate between different elements based on their unique spectral signatures.

The spectral lines of Sirius are blueshifted because the star is moving more or less toward us.
The detector in a spectrograph that records spectral lines photographically is a photographic plate or film. This photographic medium captures the light from the spectral lines dispersed by the spectrograph, allowing them to be recorded for analysis and interpretation.
Elements have several spectral lines and although some lines may be the same between different elements most lines are not and the whole spectrum for each element is indeed unique.
Yes. If the star is moving away from the Earth, its spectral lines will shift towards the red end of the spectrum. If it is moving towards the Earth, its spectral lines will shift towards the violet end of the spectrum. This is due to Doppler effect.
Yes, the chemical composition of a gas can be determined by analyzing its spectral lines. Each chemical element and molecule emits or absorbs light at specific wavelengths, creating a unique spectral signature that can be used to identify the components of a gas mixture. By studying the spectral lines produced by a gas, scientists can determine its chemical composition accurately.
The spectral lines move towards one direction, or towards the other direction, depending on the relative speed.
Spectral interference is more common in atomic emission spectroscopy due to overlapping spectral lines.
Spectral lines produced by elements are unique to each element due to differences in electron configurations. These lines represent the specific energies emitted or absorbed when electrons transition between energy levels. Analyzing these spectral lines can help identify the presence of specific elements in a sample.
Xenon has more spectral lines than helium due to its more complex electron configuration with multiple electron orbitals and subshells. This leads to a greater number of possible energy transitions for its electrons, resulting in a larger variety of spectral lines when these transitions occur. In contrast, helium has a simpler electron configuration with only two electrons, leading to fewer possible energy transitions and thus fewer spectral lines.
