discuss the role of medium in the propagation of sound
Answers
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 are additional modes of propagation). During their propagation, waves can be reflected, refracted, or attentuated by the medium. The purpose of this experiment is to examine what effect the characteristics of the medium have on sound.
Sound needs medium for its propagation . It can travel through a solid,a liquid and a gas . When an object vibrates in air,it disturbs the air particles surrounding it and causes them to vibrate. The particles present in solids and liquids also vibrate in a similarway. Sound can not propagate through a vaccum , because it does not contain any particles to pass on the vibrations.
