Question

explain how sound propagate reach to the different people

Answer 1

Sound is a sequence of waves of pressure which propagates through compressible media such as air or water. (Sound can propagate through solids as well, but there areadditional modes of propagation). During their propagation, waves can be reflected, refracted, or attentuated by the medium.

Answer 2

Sound propagates through air as a longitudinal wave. The speed of sound is determined by the properties of the air, and not by the frequency or amplitude of the sound.Sound waves, as well as most other types of waves, can be described in terms of the following basic wave phenomena.
