A single, extremely tiny unit of light known as a photon is produced when one electron in an atom undergoes a quantum drop in energy level. There are many such energy changes that electrons in the atoms of a single element can undergo, and they are all different. Furthermore, the energy changes for one element differ from the energy changes for all other elements.
Now for why this is important: The amount of energy in a photon is directly proportional to the frequency of the light or other electromagnetic radiation of that photon. Therefore, each atom produces a set of electromagnetic frequencies that represents the possible downward changes in energy levels of its electrons.

Do all light sources have the same spectra as white light?
No, white light is the combination of the entire visible light spectrum.
What are light sources and non light sources?
The sources that can give out their own light are "Light Sources" and the same opposite the sources which can not give out their own light are know as Non Light Sources .
Is it possible to have coherence between light sources emiting light of different wavelengths?
I don't think so. Coherence is defined for light of a single wavelength.
How do you produce two coherent sources of light?
two coherent light sources are produced by splitting a single light source
Can a prism refract LED light?
In the prism experiment project, you could try LED light, as well as other different light sources, like CFLs or traditional halogen light? Light is created artificially as well as by the sun. View the light from florescent light bulbs, incandescent light bulbs and colored LED lights through a prism. Notice how the light spectrum changes. Speculate on why different light sources create somewhat different light spectrums. Check to see if a second prism recombines the light into white light. Prisms unlock the secrets of light.

Why is it that different light sources have different types of spectra?
Different atoms have a different number of electrons. This is why they show different spectra.
Do all light sources have the same spectra as white light?
No, white light is the combination of the entire visible light spectrum.
What is extinction spectra?
The extinction spectra is actually the measurement of light absorption in different mediums. This spectra is used in chemistry and biochemistry.
How do scientists use different spectra to figure out the composition of the stars outer layer?
Different chemical elements emit (or absorb) certain specific frequencies of light. When the light from a star is split in to it's rainbow spectrum of light, certain parts of the spectrum will be black (in absorption spectra) or brighter (in emission spectra). By comparing these lines to the known emission and absorption spectra of elements, the composition of a stars atmosphere can be determined.
How are different types types of spectra created?
The different types of spectra are created by light shining through a prism, a glowing solid or liquid, or by a compressed/non-compressed glowing glass.
What can you now say about the spectra from various light sources?
The light source will give a spectrum that shows what elements are present. Each element will give of a particular colour, almost like a fingerprint.
What are the different color spectra of a LED?
A single LED emits light at one single frequency, so it has no spectrum.
How do you replace a 2007 KIA spectra front passenger parking light bulb?
howto change 2007 kia spectra parking light
What has the author Hermanus Pauw written?
Hermanus Pauw has written: 'Energy spectra of radioactive neutron sources' -- subject(s): Neutrons, Spectra
What are light sources and non light sources?
The sources that can give out their own light are "Light Sources" and the same opposite the sources which can not give out their own light are know as Non Light Sources .
How do different scientists spectra to figure out the composition of a star's outer layer?
The color of the light radiated by the spectra can show the internal composition as well as the gases burning on the outer layer. Red stars are colder and blue stars are hotter.
What do the white areas in the interference pattern represent?
The interference of white light creates a spectra. The different wave lengths are each diffracted to a different extent causing successive interference of the colors
