Doppler effect. is the change in frequency or pitch of a wave for an observer moving relative to its source.. Source Moving Towards Observer. Here are sound waves emanating from a motionless object. The D. ö. ppler Effect. Watch how the circles seem to be squished in the direction of motion.. The sound waves appear to be compressed (higher pitch) in the front, and extended (lower pitch) in the back. Effect & Redshift. Gharib ESS . 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. . Transport Measurement.
