Dear Student

When an element is burned it gives an emission spectrum. Since every element has different electron configurations and it is the outermost electrons that are excited by the heat energy and then relax giving off energy in the relaxation process each element emits light of a different energy (therefore wavelength) and so it is a different color.


We hope that clarifies your query.
