Question

Spectral lines are like a _____ of absorbed or emission energy in a spectrum

Options
  • A

    Charged pattern

  • B

    Fingerprint pattern

  • C

    Discharged pattern

  • D

    None of these

Explanation

Fingerprints are patterns specific to each person, therefore they can be used to identify individuals. Similarly, spectral lines act as fingerprints that allow us to identify and distinguish the matter within galaxies and heavenly bodies. By studying the light emitted from certain celestial bodies, spectral lines tell us about the presence of certain atoms and elements present within that body.
