Doppler effect. Illustration showing the bunching up of waves in front of a moving source. The source is moving from left to right. The waves behind the source are more spread out. In light sources this change in wavelength creates a blue-shift for an approaching source and a red-shift for a receding source. With sound sources it creates the change in pitch as the source moves past the observer | |
