How is atomic emission spectrum related to flame tests?

1 Answer

Atomic emission spectra are created when atoms of an element have energy added to them (by heating, or running electric current through an emission tube filled with a gas).

With the naked eye, you see a single color of light (which is the sum total of all the colors of light produced by a given element). A tool called a spectroscope will reveal the unique frequencies of light being given off by the atoms of the element.
