What is considered a characteristic of frequency in sound waves?

Frequency in sound waves refers specifically to the number of complete cycles that occur in one second. This is measured in hertz (Hz) and is a critical parameter in understanding sound waves, as it correlates with the pitch of the sound we hear. Higher frequencies result in higher-pitched sounds, while lower frequencies correspond to lower-pitched sounds.

The duration of the sound, intensity of the sound, and volume level of the sound are related to other characteristics of sound waves, but they do not define frequency. Duration describes how long the sound lasts, intensity refers to the power of the sound wave and how loud it is perceived, and volume relates to the subjective perception of loudness. Thus, focusing on the number of cycles per second distinguishes frequency as a unique aspect of sound wave characteristics.
