The wavelengths of the sound are compressed, making them shorter, and thus the frequency (and the pitch) higher. So the person in the oncoming car hears the siren operating at a higher pitch than the ambulance driver hears the same siren.
This phenomenon is known as the Doppler effect.

Modern electronic sirens change amplitude and pitch. Older sirens produced tones that changed in amplitude (volume) but were changed in pitch by their motion relative to the listener: increasing in frequency as they approached and decreasing in frequency when they moved away. This is called the Doppler Effect.
A buzzer produces different sounds by controlling the frequency and intensity of the electrical signals passing through it. By adjusting the frequency of the signal, the buzzer can produce different pitches of sound. Similarly, changing the intensity of the signal can alter the volume of the sound produced.
Overtones are higher frequency vibrations produced by an object in addition to its fundamental frequency. They are multiples of the fundamental frequency and contribute to the overall sound quality or timbre of the sound produced. Overtones are what distinguish different musical instruments or voices even when playing the same note.
Frequency waves are produced by a vibrating source, such as a sound wave produced by a vibrating object or an electromagnetic wave produced by an oscillating electric charge. The rate at which the source vibrates determines the frequency of the wave.
The tone produced by one vibration of a string is called a fundamental frequency. This fundamental frequency is the lowest frequency at which the string will vibrate, and it determines the pitch of the note that is produced.
The highest frequency in hertz that can be produced by this sound system is 20,000 Hz.
The force-frequency relationship refers to how the force produced by a muscle or system changes with the frequency of stimulation. In general, as the frequency of stimulation increases, the force produced by the muscle also increases. This relationship impacts the behavior of the system by influencing its ability to generate force and perform tasks efficiently at different frequencies of stimulation.
The frequency of vibrations in music is measured in Hertz (Hz). This unit represents the number of vibrations per second. In music, different pitches are created by varying the frequency of vibrations produced by the sound waves.
This is known as the frequency of the wave and has the unit Hertz. Hertz is capitalized because it was named after a real person.The reciprocal of frequency is the period of the wave. That is the time in seconds for one wave to pass.
The three types of timbre are bright (high-frequency emphasis), dark (low-frequency emphasis), and flat (balanced frequency distribution). Timbre refers to the unique quality of sound produced by different instruments or voices.
To measure the frequency of light accurately and effectively, you can use a device called a spectrometer. A spectrometer splits light into its different wavelengths, allowing you to determine the frequency of the light. By analyzing the spectrum produced by the spectrometer, you can accurately measure the frequency of the light.
