explain how sound waves travel in air
Answers
Hey your answer
First of all I explain how fast do speed travels in solids, liquids and gases.
Air = in 20°c 340m per second
Solids = 1500 m/ sec
Liquids = 5000 m/sec
When an object vibrates, it makes the adjacent air molecules vibrates with the same frequency. These, in turn,
transfer their vibrations to the neighbouring molecules, and this process goes on. Thus, waves of vibrations travel Al around from the vibrations travel all around from the vibrating object. This is similar to the way waves are produced in water by a stone. Just as the water waves die out after travelling some distance. The greater the amplitude of vibration, i.e. the louder the sound, the greater is the distance it will travel before dying out.
