Christian Doppler discovered the Doppler effect in 1842. He observed that the frequency of sound changes as the object of the sounds moves and the detector of the sound moves. Radar and medical devices use the Doppler effect to locate and provide images of scanned objects.

Who discovered 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.
What is the change in frequency of a sound due to motion of the source?
The change in frequency is caused by the Doppler Effect
A detected apparent change in the pitch caused by the motion of a sound source or of an observer is called?
The Doppler effect.The Doppler effect.The Doppler effect.The Doppler effect.
What is an explanation of the Doppler shift?
The Doppler Shift is a change in frequency due to the Doppler Effect.
Is true of the Doppler effect?
the Doppler effect involves moving objectsthe Doppler effect involves moving objects
Who invented Doppler radar?
Christian Doppler
When were ultrasounds invented?
in 1957 by ian Donald
What do color enhancements in Doppler ultrasounds signify?
Color enhancement is particularly useful in Doppler imaging, where shades of red signify flow away from the transducer and shades of blue signify flow toward it.
Where was the Doppler Radar invented?
At the University of Oklahoma

Why do farmers rely on the weather report?
It uses information based on the Doppler RADAR (invented and designed by Andrew Doppler) to predict weather so farmers will know when the best time to plant their cops would be.
