Absorption
spectra of the material that in certain frequencies of electromagnetic
radiation absorption of the incident presented by the ratio. In fact,
the absorption spectrum with the emission spectrum relative.
Each chemical element will be able to order in a number corresponding
to the track to generate a specific wavelength absorption lines, for
example, absorb white light in the blue, green and yellow light will
show red, the absorption lines can be used to identify the gas or
liquid contained in the element. This method can also be used to
measure the stars can not directly and other gases on the phenomenon. |
