The visual spectacle is primarily due to the emission of light by excited atoms and molecules. These particles, heated to high temperatures during the explosion, transition to higher energy states and then release this excess energy as photons when they return to their ground states. This process is known as incandescence for the hot particles and luminescence for the chemically excited ones. Different elements and compounds emit light at specific wavelengths, which is why fireworks can produce a wide range of colors: red from strontium or lithium, green from barium, blue from copper, and yellow from sodium. The auditory component of fireworks is equally fascinating. The explosion creates a shockwave that travels through the air as a pressure wave, which our ears perceive as sound. This sound wave is generated by the rapid expansion of gases produced during the chemical reaction within the firework. As these gases expand, they push against the surrounding air molecules, creating a series of compressions and rarefactions (expansions) that propagate outward from the source. The frequency and amplitude of these pressure waves determine the pitch and volume of the sound we hear. The characteristic boom or crackle of fireworks is a result of the sudden release of energy and the subsequent rapid expansion of gases. In addition to these primary effects, there are secondary phenomena that enhance our experience of fireworks. For instance, the speed of light is significantly faster than the speed of sound, which is why we see the flash of light before we hear the boom. This delay can be used to estimate the distance to the firework by measuring the time between seeing the flash and hearing the sound. Furthermore, atmospheric conditions such as temperature and humidity can affect both the visibility of light and the propagation of sound waves, influencing how we perceive fireworks displays.
