When an object moves in relation of the observer, it emits the the compressed sound waves, as it comes closer to observer and vise verse. This effect is called as Doppler effect. So you can precisely study the movement of blood across the different valves and chambers of the heart. You can give different colors to give the color Doppler effect for better understanding the flow of blood. Like wise you can see the blood flow across the deep veins of the legs and other blood vessels.
The change in frequency is caused by the Doppler Effect
Christian Doppler did not invent Doppler Radar. He described what is now known as the Doppler effect in 1842 in Austria. It is used to describe the behavior of waves (such as light or sound) that are emitted by a moving object. Doppler radar, which utilizes the Doppler effect, was developed in the United States during World War II.
The Doppler effect is useful for and used for detecting objects velocity. The Doppler radar tells whether the object is heading toward or away from you or perpendicular to you.

The Doppler effect proves that sound travels in waves.
Example sentence - We are learning to what the doppler effect is and how to use it.
The Doppler effect is the change in frequency of a sound wave. The Doppler effect causes a siren or engine to have a higher pitch when it is approaching than it does when it is receding.
