What unit of measurement is used to describe frequency in terms of cycles per second?

The correct unit of measurement for frequency in terms of cycles per second is Hertz. This unit is defined as one cycle per second and is commonly used to quantify the frequency of various phenomena, particularly in electronics and telecommunications. For instance, in the context of sound waves, a frequency of 440 Hz indicates that the sound wave completes 440 cycles in one second.

Other units mentioned relate to different properties: Joules measure energy, while Decibels quantify sound intensity or power ratio, and Bytes refer to data storage capacity. Therefore, Hertz is the precise term used for expressing frequency, making it the appropriate choice for this question.
