SUMMARY
The speed of sound in air remains constant at 340 m/s regardless of the motion of the source, such as a car moving towards a person at 50 m/s. However, the frequency of the sound emitted by the car's horn experiences a Doppler shift, resulting in a higher perceived frequency for the observer. This phenomenon illustrates the principles of sound wave propagation and the Doppler effect in physics.
