Here's a breakdown:
* Wave cycle: One complete oscillation of the wave, from its highest point (crest) to its lowest point (trough) and back to the starting point.
* Fixed point: A specific location where we observe the passing wave cycles.
The unit of frequency is Hertz (Hz), named after the German physicist Heinrich Hertz.
1 Hertz is equal to 1 wave cycle per second. So, a wave with a frequency of 10 Hz completes 10 wave cycles every second.
Example:
Imagine a buoy bobbing up and down on the ocean. If the buoy completes one full up-and-down motion every second, the frequency of the water waves is 1 Hz. If it completes two full motions per second, the frequency is 2 Hz, and so on.
Important Note:
Frequency is inversely proportional to the wavelength of a wave. This means that as the frequency increases, the wavelength decreases, and vice versa. This relationship is described by the following equation:
Frequency (f) = Speed of wave (v) / Wavelength (λ)
