Why do a observer see an explosion before they hear it?

An observer sees an explosion before hearing it because light travels much faster than sound. Light travels at approximately 299,792 kilometers per second (about 186,282 miles per second), while sound travels at about 343 meters per second (around 1,125 feet per second) in air. This significant difference in speeds means that the light from the explosion reaches the observer almost instantly, while the sound takes longer to arrive. As a result, there's a noticeable delay between seeing the explosion and hearing it.
