What is another word for atomic spectrum?
Pronunciation: [ɐtˈɒmɪk spˈɛktɹəm] (IPA) 
The "atomic spectrum" refers to the unique pattern of light emitted or absorbed by an atom when it undergoes a transition from one energy state to another. While the term "atomic spectrum" is the most commonly used phrase, there are several synonyms that can be interchangeably used. For instance, the "emission spectrum" refers to the specific wavelengths of light an atom emits, while the "absorption spectrum" describes the wavelengths of light an atom absorbs. Furthermore, "spectral lines" and "spectral bands" can be used to describe the individual lines or groups of lines within the spectrum. Finally, "atomic fingerprint" is also a popular synonym for atomic spectrum as the unique pattern of lines in each element's spectrum acts like a fingerprint, enabling researchers to identify the element.
