The number of cycles that occur in one second is defined as?

In the context of waves and cycles, frequency specifically refers to the number of cycles that occur in one second. It is measured in hertz (Hz), where one hertz equals one cycle per second. This is a fundamental concept in various fields like physics, engineering, and signal processing, making it crucial for understanding oscillatory systems, sound waves, and electromagnetic waves.

The other terms, while related to waves, describe different aspects. The period is the duration of one cycle, amplitude refers to the height of the wave, indicating the strength or intensity, and waveform describes the shape of the wave itself. Thus, frequency is distinctly defined and quantifies how often a particular event occurs in a specified time frame, clarifying its role in the study of cycles.
