Wave Properties
- Wavelength: The distance between two successive crests or troughs of a wave.
- Frequency (f): The number of waves passing by a specific point per second. The SI unit is Hertz (Hz)
- Period (T): The time it takes for one wave cycle to complete.
- Amplitude (x): The maximum displacement or distance moved by a point on a wave measured from its equilibrium position.
- Wave speed: The distance a wave travels in a given amount of time.
- Relationship between wave speed, wavelength, and frequency: Speed = Wavelength * Frequency.
