How Sound Travels through air? And why does sound travels faster with solid ?
Sound is a mechanical wave, which means that it requires a medium to propagate. It travels through the medium in the form of of changes in the density of the medium particles. As the source vibrates, the molecules near it also vibrate and this disturbance is carried forward by the medium-molecules in the form of compression and rarefaction. Thus, the sound travels as the molecules of the medium compress (come close) and rarefy (move far apart) alternately for the sound to move.
Now we know that in solids, the molecules which make up the medium are more dense than those of the air. As a result the sound wave is easily able to compress and rarefy the molecules in case of solids (due to high density of medium particles) and thus moves faster.
