What is an emission spectra used for?
The emission spectrum can be used to determine the composition of a material
How Many types of Infrared Spectra?
There are three main types of infrared spectra: absorption spectra, emission spectra, and reflection spectra. Absorption spectra are produced when a material absorbs infrared energy, emission spectra are produced when a material emits infrared radiation, and reflection spectra result from the reflection of infrared radiation off a material.
Who discovered the atomic emission spectra?
thomas Jefferson
What is a continuous spectra?
an emission spectrum that consists of a continuum of wavelengths.
Why are emission spectra called the fingerprints of the elements?
Because an emission spectrum is specific to an element.It can be used to identify the element
What are the similarities between emission and absorption spectra?
The lines are at the same frequencies
What examples of everyday objects with vivid emission spectra?
Some examples of every day objects with vivid emission spectra are the following: glass, water droplets, and chameleon paint jobs.
What is the difference between absorption and emission spectrum?
Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.
What two sources of continuous spectra will be use in emission spectroscopy?
Two common sources of continuous spectra used in emission spectroscopy are the electrical discharge lamps and the incandescent lamps. Electrical discharge lamps, such as the mercury vapor lamps, produce continuous spectra due to the excitation of atoms or molecules in the gas discharge. Incandescent lamps, on the other hand, produce continuous spectra because of the thermal emission from the hot filament.
Scientist use the emission spectra of element to detect?
Emission spectrometry is an old and largely known method for quantitative and qualitative analysis of elements.
How would the spectra from galaxies appear?
They have broad emission lines of highly ionized elements.
Why is the study of spectra so important?
It is used to see the colours that it gives off, if you know the colours you then know what atom it is.
