WebA bright line, or emission spectrum, appears as a pattern or series of bright lines; it consists of light in which only certain discrete wavelengths are present. ( Figure 5.11 shows an absorption spectrum, whereas Figure 5.12 shows the emission spectrum of a number of common elements along with an example of a continuous spectrum.) WebThe emission spectrum is the set of light frequencies emitted by substances after they have been excited with various forms of energy, most commonly heat or electrical. ...
