The relationship of Hertz to sound waves to cycles per second is best described as?

Hertz (Hz) is a unit of frequency that measures the number of cycles per second of a periodic wave, including sound waves. Therefore, it essentially defines one cycle per second. This means that when we say a sound is at a frequency of 100 Hz, it indicates that the sound wave completes 100 cycles in one second.

In the context of this question, saying there is a 1:1:1 relationship implies that one Hertz equals one cycle per second, emphasizing the direct and straightforward conversion between these two concepts. Thus, every time you see a frequency measured in Hertz, it is precisely indicating how many complete cycles occur in each second.

This fundamental understanding of frequency is critical when studying sound waves and auditory perception, as it lays the groundwork for further exploration into topics such as pitch and sound modulation that are directly affected by frequency.
