types of sound and their definition
Answers
Explanation:
Sound waves need a medium (or material) to travel through. These kindsof vibrational waves have another name: longitudinal waves. In fact, there are two main types of waves: transverse and longitudinal. Longitudinal waves are where the vibration moves parallel to the direction the wave is traveling.
Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed.

Answer:
Sound, a mechanical disturbance from a state of equilibrium that propagates through an elastic material medium. A purely subjective definition of sound is also possible, as that which is perceived by the ear, but such a definition is not particularly illuminating and is unduly restrictive, for it is useful to speak of sounds that cannot be heard by the human ear, such as those that are produced by dog whistles or by sonar equipment.
