which describes a scenario in which the doppler effect is occurring? the volume increases. the pitch changes from low to high. the pitch changes from high to low. the volume decreases.
Answer
Brief Explanations:
The Doppler effect is related to the change in frequency (pitch) of a wave due to relative motion between the source and the observer. When a source moves away from an observer, the pitch changes from high to low. When it moves towards the observer, the pitch changes from low to high. Volume is related to amplitude and not the Doppler - effect.
Answer:
The pitch changes from low to high; The pitch changes from high to low
