What is propogation of sound?????

1.	What is propogation of sound?????
Answer» \t\xa0Sound waves move from the point of generation to the listener through the medium.\tWhen an object vibrates and produces sound, the particles of the medium at the point of generation begin to vibrate.\tThis particle passes on the vibration to its adjacent/neighboring particle. The first particle comes back to its equilibrium position of rest. Then the second particles passes its vibration to the neighboring third particle and then again comes back to its position of rest. This process continues until the vibration reaches the listener and he is able to hear the sound.\tAs we see, the actual particles of the medium don\'t travel from the point of generation to listener. It is only the vibration that travels through the medium. This is called Wave motion.\tA wave is a disturbance that moves through a medium when the particles of the medium set neighboring particles into motion. Since sound waves are characterized by the motion of particles in the medium, they are Mechanical Waves. Propagation of sound is the passing or transportation of sound through a medium it may be solid ,liqid or gas.
