Generation

The Doppler effect is the change in frequency (or pitch) of a wave that occurs when the source of the wave and the observer are moving relative to each other. When the source moves toward you, the waves get compressed, resulting in a higher frequency—like how an approaching ambulance siren sounds higher-pitched. When the source moves away, the waves get stretched out, creating a lower frequency—the siren sounds lower as it passes. This effect occurs with all types of waves, including sound waves and light waves (where it causes redshift and blueshift in astronomy).
