What is an atomic spectrum?
Atomic spectrum is the spectrum of frequencies or wavelengths of radiations absorbed or emitted when electrons transitions between on energyblevel to another.
The estimated wavelengths as well as identities of the elements of spectral lines shown above are as follows
- blue spectral line - 470 nm;
- green spectral line - 490 nm; Iron
- yellow spectral line - 610 nm; Sodium
- red spectral line - 660 nm; Hydrogen
Therefore, the wavelengths and colors of the spectral line in an atomic spectrum is useful in identifying elements.
