Answer:
Explanation:
Here, we want to get the relationship between elements used in fireworks and the line spectrum.
The use of fireworks typically involves the application of a source of heat or fire to the fireworks. When this happens, excitation also occurs. The excitation that occurs is also accompanied by a relaxation.
This energy level change would lead to a color change which relies on the energy difference level of the line spectrum and thereby showing the appropriate colour
