So what's the correct formula?berkeman said:
Frequency of Siren is 988Hzberkeman said:
You are the student, so you must tell us that.ThePhysicsXV said:
That does not fully answer my question. That is the frequency that is heard how? When the car is approaching, or when it is stopped and you are stopped. Please post the full text of the question.ThePhysicsXV said:

The frequency of a police siren can vary, but it is typically between 500 and 1000 Hz.
The frequency of a police siren increases as it approaches and decreases as it moves away due to the Doppler effect.
The frequency of a police siren changes due to the Doppler effect, which is caused by the relative motion between the source of the sound waves and the observer.
The speed of the police car affects the frequency of the siren by changing the rate at which the sound waves are emitted.
The formula for calculating the frequency of a passing police siren is f = (v / v ± u) * f₀, where f is the observed frequency, v is the speed of sound, u is the speed of the police car, and f₀ is the frequency of the siren at rest.
