In the context of waves, what is frequency?

Frequency refers to the number of cycles, or complete wave oscillations, that pass a given point in a specific period of time, typically measured in seconds. This concept is fundamental in the study of waves, as it directly affects the perceived pitch of sound and the color of light, among other wave phenomena. A higher frequency means more cycles pass through a point each second, resulting in a higher energy wave. Conversely, a lower frequency indicates fewer cycles per second, corresponding to lower energy.

When dealing with sound waves, for example, the frequency helps determine how high or low a sound is perceived by the human ear. Thus, understanding frequency is crucial for anyone studying wave properties, as it establishes the relationship between the wave's oscillations and its broader characteristics in various media.
