Key Points
- Amplitude is the maximum displacement of a wave from its resting position
- Wavelength is the distance between two consecutive crests or troughs of a wave
- Frequency is the number of waves that pass a given point per unit of time
- Period is the time taken for one complete wave cycle to pass a given point
- Wave speed is the distance traveled by a wave per unit of time
Amplitude
Amplitude is the maximum displacement of a wave from its resting position.
Wavelength
Wavelength is the distance between two consecutive crests or troughs of a wave.
Frequency
Frequency is the number of waves that pass a given point per unit of time. It is measured in Hertz (Hz).
Period
Period is the time taken for one complete wave cycle to pass a given point. It is the inverse of frequency.
Speed
Wave speed is the distance traveled by a wave per unit of time. It is calculated as the product of wavelength and frequency.
