Below is shown the emission spectra of the first four elements in the periodic table: Hydrogen, Helium, Lithium, and Beryllium.
The scale is in nanometers. Notice that the location, and pattern, of lines is unique to each element.
Below is shown the absorption spectra of the first four elements in the periodic table: Hydrogen, Helium, Lithium, and Beryllium.
The scale is in nanometers. Notice that the location, and pattern, of lines is the same as shown above.
