The sound of thunder is not uniform; it varies based on how far a listener is from the lightning strike. This variation is influenced by the atmosphere, which can muffle and absorb sound waves.
When lightning occurs, it can heat the surrounding air to nearly 30,000°C. This rapid heating causes the air to expand explosively, creating the thunderous sound we hear.
Understanding these factors helps us appreciate the complexity of thunder and its relationship with lightning, as well as the role of atmospheric conditions in sound propagation.
