Characteristics of waves:
1. All waves have speed which depends on the nature of disturbance.
2. All waves have wavelength (distance between two successive points in a wave).
3. All waves have frequency ‘f’ which is the number of waves passing a point in one second. It is measured in cycles per second or hertz (Hz).
4. All waves have amplitude which is the maximum displacement of the particles of the medium as the wave passes.
