18. What is the explanation for the discrete lines in atomic emission spectra? How did this affect the model of the atom?
An atomic emission spectrum is obtained by splitting the light emitted from an atom with a prism. This forms discrete lines with their own color (frequency), which each correspond to a certain quantum of energy.
This means that electrons could only be found in very specific energy levels rather than just floating around wherever they wanted.
Bohr formed his progressive (and incorrect) model of the atom by observing the atomic emission spectrum of hydrogen.
