The phase shift effect is similar to the Doppler shift observed with sound waves. With the Doppler shift, the sound pitch of an object moving toward your location is higher due to compression of sound waves. As an object moves away from your location, sound waves are stretched resulting in a lower frequency.
The Doppler Effect. The Doppler effect was named after Christian Doppler, who first came up with the idea in 1842. He learned that sound waves would have a higher frequency if the source was moving toward the observer and a lower freqency if the source was moving away from the observer. A commonly used example of the Doppler effect is a train. When a train is approaching, the whistle has a higher pitch than normal. You can hear the change in pitch as the train passes. The same is true with sirens on police cars and the engines of race cars.
