What is defined as the number of waves generated per second?

Frequency is defined as the number of waves generated per second. It quantifies how often a wave cycle occurs in a given timeframe, typically measured in Hertz (Hz), which represents one cycle per second.

Understanding frequency is crucial in various fields, including physics, telecommunications, and aviation, particularly when assessing how signals propagate through the air or how sound is transmitted. In the context of unmanned aerial systems, frequency may also relate to the operational characteristics of communication systems, where ensuring compatible frequencies can prevent interference and allow for the effective control of drones.

Amplitude refers to the height of the waves, indicating the wave's strength or intensity but not its rate of occurrence. Wavelength denotes the distance between successive crests (or troughs) of a wave, which does not determine how frequently the waves occur. The period is the duration of time it takes for one complete wave cycle to occur, which is inversely related to frequency; while they are related, it does not directly describe the number of waves per second. Thus, frequency is the most accurate term for the number of waves generated in that time interval.
