What is multiplicity of spectral line?
no
What does line spectrum tell us?
The bright line emission spectrum tells us the amount of energy between the exited and ground state. When electrons move from an exited state to a ground state, radiant energy of a specific frequency is emitted this creates spectral lines.
Parameter which boarding the spectral line?
You think probable to the wavelength.
What is the color of the spectral line with a wavelength of 502 nanometers?
Green.
Why do element have a number of spectral lines?
Elements have a number of spectral lines because of the number of energy levels and electrons. An electron falling from n=2 to n=1 gives one line, and if it falls from n=3 to n=1, it gives yet another line, and so on.
How is the bright light spectra of elements produced?
An emission or absorption line in a spectrum that arises when an electron moves between two energy levels in an atom. A jump to a higher level requires an input of energy, and produces a dark absorption line. A drop to a lower level releases energy, producing a bright emission line.
What is multiplicity of spectral line?
no
Why are some spectral lines thicker than others?
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.
How is spectral analysis used in light sources?
Spectral analysis is a procedure in which a light source is shone through a lens to reveal its components. Light created by different methods have different spectral components, which act like a fingerprint. For example, if you examine the spectrum of a distant star, the different wavelengths will show you what different elements comprise that star. At a more detailed scientific level, the individual lines are determined by the amount of energy lost by a particular atom's electrons as they move between energy levels. Each energy level of an atom's electron shell is characteristic to that atom. When an electron moves from a higher energy level to a lower one, there is a release of energy in the form of a photon, and that photon's wavelength is determined by the amount of energy change, resulting in a spectrographic line characteristic to that atom.
What type of line does the photon move in?
Spectral line
How is a line in a graph related to energy?
There is no need for the line to be related to energy. The line in the graph could represent height against age of adults. No relation to energy, I'd suggest.
How does the intensity of the spectral line yield information about the source of the line?
Intensity of spectral line show the abundance of different elements in the light source. Every element has its own "fingerprint" which can indicate its presence.
How many spectral lines are emitted if an electron moves from the L shell to the K shell?
Since the K is 1 level below the L, only one photon (at 1 specific wavelength) will emit. So you will only see 1 spectral line.
Parameter which boarding the spectral line?
You think probable to the wavelength.
What is the color of the spectral line with a wavelength of 502 nanometers?
Green.
What does line spectrum tell us?
The bright line emission spectrum tells us the amount of energy between the exited and ground state. When electrons move from an exited state to a ground state, radiant energy of a specific frequency is emitted this creates spectral lines.
You observe the same spectral line in two stars that are identical in every way except that one rotates faster than the other How does the spectral line differ between the two?
The line in the faster rotating star is broader.
