As a wave source approaches, an observer encounters waves with a higher frequency. As the wave source moves away, an observer encounters waves with a lower frequency. . Students will learn about the Doppler Effect. Doppler Effect (J. C. Doppler, 1842). Applies to all waves. If there is motion between the source and the observer.. If the distance between the source and the observer decreases, the “perceived” frequency increases (higher pitch).. Transport Measurement. Mike Hardesty. 1,4. , . Sara Tucker. 4*. ,.
