WHAT YOU NEED TO KNOW..
When heated to high temperatures, elements and compounds will emit light. The light that is emitted is always the same color. Some elements emit more than one color, but these secondary colors are always the same.
This is helpful to scientists because when ever they look at the spectrum of a material he can plot these bright emission lines, determine their wavelengths, and compare them with known samples of spectra of known elements.
