In a spectral line from a rotating body such as a star, some of the matter emitting the line is moving toward you and has a part of its line shifted slightly to the bluer end of the spectrum, some is moving away and has a slight shift toward the red end, and the rest is moving more or less across your line of sight and the shift is normal.
What else can I help you with?
How might the difference in the brightness of spectral lines be explained?
Different quantities of the materials producing the lines.Some lines are weaker because the electron transitions producing them are less likely.Some lines are stronger or weaker depending upon the temperature of the material producing the lines (a big issue in determining stellar spectral classes).Different quantities of the materials producing the lines. Some lines are weaker because the electron transitions producing MORE?The distribution of photon energies, which have a peak at a wavelength that depends on temperature (ref. 1).Also differing amounts or concentrations of the elements responsible for those lines.
Suppose you want to know the chemical composition of a distant star Which piece of information is most useful to you?
The star's absorption spectrum would be most useful in determining its chemical composition. By studying the specific wavelengths of light that are absorbed by elements in the star's atmosphere, scientists can identify the presence of different elements and molecules.
Why does hydrogen atom contain many lines?
When the energy is supplied to the atom of hydrogen it will be exited then its single electron will jump from its ground state to some higher energy level. Now,when it de exites from higher level to ground level by several jumps pectral lines of different wavelengths are emitted. That is why the spectrum of hydrogen contains many lines.
What is it called when you give to others some of what you have?
Sharing.
What materials are being used to replace copper telephone and cable television lines?
Fiber-optic cables are commonly being used to replace copper telephone and cable television lines. These cables use light to transmit data at high speeds over long distances, offering faster and more reliable connections compared to copper lines. Additionally, some providers are exploring the use of wireless technology like 5G for delivering telephone and television services.
Does Every element and compound in nature have a unique set of spectral lines?
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.
Why are some contours thicker than others?
Contour lines represent elevation on a topographic map. Thicker contour lines are known as index contours and typically represent a significant change in elevation, such as a peak or ridge. They help the reader quickly identify major landforms on the map.
What are the dark lines in a stellar spectrum are called?
Fraunhofer realised that some of these dark lines were at the same position in effect called the Zeeman effect can also cause splitting of the spectral lines.

Why do people have monobrows?
Some people just have eyebrows that tend to grow more thickly in the center than others do, just as some have thicker hair on their head than others do.
How can I see an line spectrum from a cloud of gas?
If there is a star shining through the gas then some of the starlight will be absorbed by the gas to deliver spectral lines of the "stuff" making up the gas.
Why are some power cords thicker than others?
It has to do with current requirements of whatever you plug into it. Things that heat up require a thicker cord to transport the current. A thinner cord may overheat.
Is a hoop earring thicker than a lip ring?
It depends how large it is, some of them are and others aren't Hoped I helped.<3
What are some star characteristics that can be identified by spectral analysis?
Some star characteristics that can be identified by spectral analysis include temperature, composition, mass, luminosity, and age. By analyzing the lines present in a star's spectrum, astronomers can determine these key properties and gain insights into the star's physical characteristics and evolutionary stage.
How thick were castle walls?
Some were thicker than others. It also depended on how protected you want your castle to be. Also if you had enough money.
Why do some fiber work better than others to keep you warm?
Some fibers work better than other to keep you warm because they are thicker.
Are some pennies thicker than others?
yes; if you look closely it is very easy to tell
