what is the importance of air in transmission of sound?
Answers
Answer:
The air is the medium which is necessary for the transmission of sound.
The sound needs a medium to propagate and air provides that medium.
Sound waves are created by help of the disturbances in the medium. The individual particles in the air are not transmitted with the wave, but actually the propagation of the wave is what causes the particles, i.e. (molecules of the air) oscillate about an equilibrium position.
The sound travels in the form of longitudinal wave in the medium. That is the energy is first passed on to the next molecule and then the molecule passes the energy to the subsequent molecule and this is how the transmission takes place inside of the air.
The speed of the sound in the air is 343 m/s and even greater in the liquids and the greatest in the solid.
Answer:
Air acts as a medium for transmission of sound. When a sound wave passes through air, the particles of air vibrate back and forth, parallel to the direction of the sound wave.Sound waves are created by a disturbance that then propagates through a medium ( e.g., crust, water, air).The source of a sound vibrates, bumping into nearby air molecules which in turn bump into their neighbours, and so forth. This results in a wave of vibrations travelling through the air to the eardrum, which in turn also vibrates.The speed of propagation of a sound wave is dependent upon the density of the medium of transmission. Weather conditions (e.g., temperature, pressure, humidity, etc.) and certain geophysical topographical features (e.g., mountains or hills) can obstruct sound transmission.
