In this lab you observed that each element emits a unique color of light when heated in a flame. if these light emissions were examined through a prism, you would observe that the emitted light is actually composed of different wavelengths of light that may lie in the violet region, the green region, or the red region of the visible spectrum. each element has a unique emission spectrum. look up the emission spectra for the element tested in this lab. do research on how scientists apply these emission spectra to investigate the chemical composition pf stars. for example what is the emission spectrum of the sun, and what does this spectrum reveal about the types of elements in the sun
