SUMMARY
The speed of sound in air is consistently 340 m/s, regardless of the speed of the source, such as a jet moving at 100 m/s. This phenomenon is explained by the principle that wave velocity is independent of the source's motion relative to the medium. The discussion highlights a common misconception that wave velocity is dependent on the medium, clarifying that the speed of sound remains constant in a given medium, which in this case is air.
