Expert Solution

Step 1

Introduction:

Sound wave is the longitudinal wave. For the propagation of the sound material medium is require. When sound wave is propagated through the medium, compression and expansion of the medium is takes place. Pitch of sound refers to how high or low sound is. Pitch of the sound depends on the position of the source and observation. Another factor which decides the pitch of the sound is the relative velocity of the source and observer.
