* Wavelength (λ): The distance between two successive crests (or troughs) of a wave. This is often measured in meters (m), centimeters (cm), or nanometers (nm).
* Frequency (f): The number of waves that pass a given point per unit of time. This is usually measured in Hertz (Hz), where 1 Hz is equal to one wave per second.
* Amplitude (A): The maximum displacement of a point on the wave from its equilibrium position. This is measured in the same units as the wave's displacement (e.g., meters, centimeters).
* Period (T): The time it takes for one complete wave cycle to pass a given point. This is the inverse of frequency and is measured in seconds (s).
These measurements are related by the following equation:
v = fλ
Where:
* v is the wave speed (m/s)
* f is the frequency (Hz)
* λ is the wavelength (m)
So, while a periodic wave can be measured in terms of its wavelength, frequency, amplitude, and period, understanding the relationship between these measurements is crucial to fully grasp its behavior.
