Question: 1 / 400

What is equivalent to one Hertz (Hz)?

One mile per hour

One cycle per second

One Hertz (Hz) is defined as one cycle per second. This means that if something occurs at a frequency of one Hz, it completes one full cycle of a periodic phenomenon in one second. For instance, if you consider a wave, having a frequency of one Hz means that the wave oscillates or repeats its cycle once within that time frame.

Understanding this concept is critical in various fields such as physics, engineering, and telecommunications, where frequency plays a crucial role in wave behavior, signal processing, and more. Other options, such as miles per hour, wavelengths, and amperes, pertain to entirely different measurements and do not relate to frequency in the same way. Therefore, the correct interpretation of Hertz directly aligns with the notion of cycles per second, solidifying option B as the correct choice.
