Sound Wave Properties - 10

A sound wave is produced by a mechanically vibrating source in a medium. Its energy is transferred from one point to another without a transfer of medium

it is a type of longitudinal wave that travels parallel to the vibration of the medium.

The layers of air are pushed close together, producing compression and rise in air pressure

The layers of air are pulled apart, producing rarefaction and fall in air pressure.

It is a region where air pressure is higher than the surrrounding air pressure

It is a region where air pressure is lower than the surrounding air pressure

20 compressions and rarefactions in 1 second

No, it requires a medium to propagate

air: 300-340m/s liquid: 1500-1600m/s solid: 5000-6000m/s

Sound waves transfer energy through collisions of particles. Particles in solids are closely packled hence the rate of sound energy will be transfered faster compared to air and liquid
