Finally, examine the atomic spectrum below. Estimate the wavelength
of each spectral line, then use that collection of wavelengths to try and
determine the identity of the element using the internet. This is the
kind of work a graduate student in chemistry might be assigned to do.

The estimated wavelengths and identities of the elements of spectral line in the given atomic spectrum is:

  • blue spectral line - 470 nm; Iron
  • green spectral line - 490 nm; Magnesium
  • yellow spectral line - 610 nm; Sodium
  • red spectral line - 660 nm; Hydrogen

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.
