SUMMARY
The discussion centers on the Doppler effect as it applies to sound frequency changes due to relative motion. A car traveling at 30 m/s approaches a stationary sound source emitting a frequency of 5000 Hz, resulting in an apparent frequency of 5455 Hz as calculated using the formula ((330+30)/330) x 5000. However, when considering the reflection of sound from the car, the frequency perceived by the car is not the same as the frequency it reflects, leading to a frequency of 6001 Hz being noted as the apparent frequency reflected from the car.
