The Doppler effect is the change in frequency of sound waves as a sound source or listener moves relative to each other. When a source is moving towards a listener, the frequency appears higher (shorter wavelength) due to compression of waves. When moving away, the frequency seems lower (longer wavelength) due to stretching of waves.

What do you call the change in sound frequency due to a relative motion?
The Doppler Effect.
Does the wave speed change in the Doppler effect?
No, the wave speed does not change in the Doppler effect. The apparent frequency and wavelength of the wave change due to the motion of the source or observer relative to the wave, but the speed of the wave remains constant.
What is the change in frequency of a sound due to motion of the source?
The change in frequency of a sound due to motion of the source is called the Doppler effect. If the source is moving towards the observer, the frequency of the sound appears higher (blueshifted), while if the source is moving away, the frequency appears lower (redshifted). This effect is commonly experienced with passing vehicles and sirens.
What would be an observable change in sound when the frequency changes?
An observable change in sound when the frequency changes is a difference in pitch. As the frequency increases, the pitch becomes higher, and as the frequency decreases, the pitch becomes lower. This change in pitch is due to the direct relationship between frequency and pitch in sound waves.
If you are moving toward the source of a sound wave and then pass the source and continue moving away the will change.?
As you move toward the source of a sound wave, the frequency of the sound will appear to increase due to the Doppler effect. Once you pass the source and move away from it, the frequency of the sound will appear to decrease. The change in frequency is a result of the relative motion between you and the sound source.
