Fireworks are a beautiful display of exploding colorful lights that delight people of all ages. Fireworks get their colors when the energy of the firework's explosion excites the atoms inside the firework.
Each atom has a unique pattern of electrons orbiting around a nucleus made up of protons and neutrons. When the firework explodes, the heat and energy from the explosion excites the electrons and causes them to jump to higher energy levels. As the electrons return to their original energy levels, they release the energy that they received as light.
Different elements that are present in the firework produce different colors of light. For example, when the element strontium is present, it releases a bright red color. The element copper produces a blue color, and potassium produces a purple color.
The energy levels of the atoms determine the color of light that is released. When an electron moves from a higher energy level to a lower energy level, it releases a specific amount of light energy. This energy has a specific wavelength and frequency, which determines the color that we see.
To summarize, fireworks get their vibrant colors when atoms are excited by the energy of the explosion, and as the atoms return to their original energy levels, they release the energy as light of different colors.
