In chemistry, none. Spectra can be the plural of spectrum, it is an oddity because it can also be a singular of spectrum. It refers to particular wavelengths in many fields. It can also refer to other things depending on context.
Fun word. Careful how you use it. Ain't English great?
What else can I help you with?
Is the spacing between the lines in the spectrum of an element constant or does it vary?
The spacing between the lines in the spectrum of an element are constant. This is called the emission spectrum of an element. Each element has a unique emission spectra that will be the same each time.
What is the difference between NOEsy spectra or NOE difference spectra?
NOESY spectra provide information on through-space interactions between protons, showing correlations between protons that are close in space. NOE difference spectra compare two spectra to highlight differences in nuclear Overhauser effect (NOE) intensities between two conditions, such as before and after a perturbation, revealing changes in molecular structure or dynamics.
What is an emission spectra used for?
An emission spectrum is used to identify elements present in a sample by measuring the specific wavelengths of light emitted when the atoms are excited. This can be helpful in areas such as astronomy, chemistry, and material science for determining the composition of a substance.
How can emission spectra used to identify presence of specific elements in a substance?
In atomic spectroscopy, each element has a unique spectrum. The atomic spectrum obtained from a sample is a combination of the spectra of each elemental component. We take the strongest line from the sample spectrum and determine which elements could have caused it (we call these "candidates"). We then look at the full spectrum from each candidate and see whether or not every major line is present in the sample spectrum. If so, we say that element is present.Then we subtract the spectrum (or spectra) of the element(s) we have determined to be present from the sample spectrum and repeat the same process with the next strongest line in the (leftover) sample spectrum. We continue repeating this process until all lines in the sample spectrum are accounted for.
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 has the author A E Gillam written?
A. E. Gillam has written: 'Introduction to electronic absorption spectroscopy in organic chemistry' -- subject(s): Absorption spectra, Organic Chemistry, Spectrum analysis 'An introduction to electronic absorption spectroscopy in organic chemistry' -- subject(s): Absorption spectra, Analytic Chemistry, Organic Chemistry, Physical and theoretical Chemistry, Spectrum analysis
What is the plural form of the spectrum?
The plural of spectrum is "spectra."
What is the difference between absorption and emission spectrum?
Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.
Is the spacing between the lines in the spectrum of an element constant or does it vary?
The spacing between the lines in the spectrum of an element are constant. This is called the emission spectrum of an element. Each element has a unique emission spectra that will be the same each time.
What is the difference between the different polaroid spectra cameras?
The best place for information on the Polaroid Spectra cameras is camerapedia.org.
What is the difference between NOEsy spectra or NOE difference spectra?
NOESY spectra provide information on through-space interactions between protons, showing correlations between protons that are close in space. NOE difference spectra compare two spectra to highlight differences in nuclear Overhauser effect (NOE) intensities between two conditions, such as before and after a perturbation, revealing changes in molecular structure or dynamics.
What do you call a prism spreading out light into colors?
It is called Visible light Spectrum.
What is an emission spectra used for?
An emission spectrum is used to identify elements present in a sample by measuring the specific wavelengths of light emitted when the atoms are excited. This can be helpful in areas such as astronomy, chemistry, and material science for determining the composition of a substance.
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.
What is the difference between the spectra of different gas tubes?
They have different packaged particles.
What is the plural of the word spectra?
Spectra is the plural of spectrum. You could discuss the spectrum generated by an element in a star, and comparing more than one element, you would be comparing spectra. (Latin -um words form plurals like this, so you cannot refer to them as spectrums. Another example is datum, singular, and data, plural.)
What is main difference between prism spectrum and grating spectrum?
Prism spectrum is formed due to DISPERSION but grating spectrum is formed due to DIFFRACTION. In prism spectrum we have only one order but in grating spectrum we can have second order too IN prism spectrum we have continuous spectrum but in gratings we have only line spectrum In prism spectrum red end will be closer to the direct ray but in grating spectrum violet end will be closer to the direct ray
