How is the light of an emission spectrum of an element produced?

Basically, energy is emitted when an electron falls from a higher energy level to a lower energy level. Such energy is emitted as electromagnetic waves, which in certain cases can be visible light.

What spectum is obtained When any element in the gas phase is excited to the point where it emits visible light?
When any element is excited to the point where it emits visible light, it emits a unique spectrum. The mercury in a florescent lamp emits a spectrum in the ultraviolet spectrum. It excites phosphorus powder on the inside of the bulb. The ultraviolet rays strike the phosphorus and it emits white light. Sodium emits yellow light. Potassium emits purple light. Sodium actually emits two different yellows. Each element emits several different colors.The above is not wrong, but it doesn't really answer the question. I believe the answer the poster was looking for is emission spectrum.You may be correct. I have no intention of giving the emission spectrum of every element. I only wished to help the questioner understand what happens when an emission spectrum is produced. I had the idea that the questioner had the idea that every element produced the same emission spectrum. We interpreted the question differently.
How does an emission spectrum of a gas in a discharge tube differ from a white light spectrum?
It differs by that white light spectrum is continuous and consists of light of all wavelengths. Emission spectrum is not continuous. It consists of bright lines at specific wavelengths, with complete darkness between them.
What is the difference between absorption and emission spectrum?
Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.
What colors of visible light are found in the emission spectrum of hydrogen?
Red, blue, green, and violet are found in the emission spectrum of hydrogen.
Which type of spectrum is produced when light from the sun passes through a prism?
It is the spectrum of visible light, which has the colors of the rainbow.
Explain the difference between the continuous spectrum of white light and the atomic emission spectrum of an element?
The difference between continuous spectrum and the atomic emission espectrum of an element is that in emission spectrum, only certain specific frequencies of light are emitted while in a continuous spectrum, a continuous range of colors are seen in the visible light.

How is an emission spectrum of an element generated?
All hot solids or dense enough gases emit black body radiation. Gases that are not very dense are are cold absorb particular wavelengths while gases that are not dense but are hot produce their characteristic emission spectrum.
What are Frequencies of light emitted by an element called?
"Spectrogram" is a word used to describe the set of specific characteristic frequencies of light which are emitted by a given chemical element when it is sufficiently excited by heat or by some other means.Alternatively, a scientific technique known as "spectroscopy" can be used to identify the elements in some matter of unknown composition and also the emission spectra of molecules can be used in chemical analysis of substances.Because each element's emission spectrum is unique, the "emission spectrum" of a chemical element or chemical compound can be used to help identify what it is. The "emission spectrum" is the name given to the relative intensity of each frequency of electromagnetic radiation http://www.answers.com/topic/emission-spectrum by the element's atoms or a compound's molecules when they are returned to a ground state.
How can you Distinguish absorption spectrum from emission spectrum?
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
What is the atomic emission spectra?
The colors of light given off when an element loses energy
The lines in the bright line spectrum of an atom are due to what?
The atomic line spectrum comes from the emission of atoms of different elements that are in an excited state. Each element has its own unique atomic emission spectrum.
Why do different elements give off a colorful light when heated?
The color depends on the lines of the emission spectrum of each different element.
How does an emission spectrum of a gas in a discharge tube differ from a white light spectrum?
It differs by that white light spectrum is continuous and consists of light of all wavelengths. Emission spectrum is not continuous. It consists of bright lines at specific wavelengths, with complete darkness between them.
The bright-line spectrum produced by the excited atoms of an element contains wavelengths that are?
in the visible light range
What is the difference between absorption and emission spectrum?
Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.
What type of spectrum does an incandescent light produce?
There are no bright lines and no dark lines in the spectrum, incandescent light has a continuous spectrum with all visible colors present
