What is the definition of Frequency?

Frequency is defined as the number of cycles or wavelengths of a wave that occur in one second, measured in hertz (Hz). This concept is critical in understanding the behavior of sound waves, especially in oceanographic and acoustic contexts. Higher frequencies correspond to a greater number of cycles occurring in a given timeframe, impacting both the characteristics of the sound and how it interacts with the environment.

For example, in underwater acoustics, different frequencies affect how sound propagates through water, influencing detection and communication capabilities in marine environments. Therefore, knowing that frequency pertains to the repetition of sound waves over time is essential for applications in acoustics and oceanography. Understanding this definition helps clarify concepts related to sound wave behavior and the science behind various acoustic phenomena.
