The frequency of a sound wave created by a moving object will increase if the object is moving towards the observer and decrease if the object is moving away. This effect is known as the Doppler effect.
Sound wave is an example of a purely longitudinal wave. In a sound wave, the particles of the medium vibrate in the same direction as the wave is moving, creating compressions and rarefactions as the wave travels through the medium.
Sound is a form of energy derived from moving objects. Vibrations in air made by moving objects create sound waves.
When a sound wave hits an object, it causes the object to vibrate at the same frequency as the sound wave. This can sometimes be seen as the object physically moving, especially if the sound wave has a high intensity or frequency.

It is also known as a compression wave
Longitudinal waves are waves in which the particles of the medium vibrate back and forth in the same direction as the wave is moving. Sound waves are a type of longitudinal wave, where the vibrations of air particles create the sensation of sound. Sound waves travel through a medium, such as air, by compressing and rarefying the particles in the same direction as the wave is moving.
