Question

What are the various applications of dopplers effect?​

Answer 1

Hi my dear friend,

In medicine, the Doppler Effect can be used to measure the direction and speed of blood flow in arteries and veins. This is used in echocardiograms and medical ultrasonography and is an effective tool in diagnosis of vascular problems.

Answer 2

Doppler's effect can be defined as an observed change in frequency of a wave when an observer and source have a relative motion between them. In other words, it is an increase or decrease in the frequency of waves (for example - sound or light) as the source and observer move toward or away from each other.

This phenomenon was named after the Austrian physist, Christian Doppler, who proposed it in 1842 during his time at Prague Polytechnic University.
