The characteristics of waves are explained below
Explanation:
All waves are a form of a disturbance caused by external vibration that transfers energy and travel from one end to another in a fluid medium.
They involve the transport of energy without transport of matter.
A wave is described by its length, frequency and height (amplitude).
All waves possess the same basic fundamental properties of reflection, refraction, diffraction, and interference.
All waves have a wavelength, frequency, speed, period and amplitude.
