Quizplus · Accepted Answer

The Doppler effect refers to the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. This can apply to sound waves, light waves, and other types of waves. If a person is moving toward a sound source, the frequency of the sound waves they hear will increase, causing the pitch to rise. Therefore, the statement is true.
