The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. It causes a shift in frequency when the source of the wave and the observer are moving towards or away from each other. This effect is commonly observed with sound waves, such as the change in pitch of a siren as an ambulance passes by.

Doppler effect
The Doppler Effect is the change in frequency of a wave due to the relative motion between the source and observer. For light waves, the Doppler Effect is primarily related to the velocity of the source or observer; the wavelength of light does not significantly affect the Doppler Effect. As the source or observer move toward each other, the perceived wavelength decreases (blue shift), while moving away from each other results in increased wavelength (red shift).
It is not true that the Doppler effect has anything to do with electricity and the flow of current. The Doppler effect involves pitch and sound frequency of moving objects, for example the apparent noise changes of an approaching car.
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.

Yes that is true! Astronomy homework?
Doppler effect and Doppler radar are the two most common compound nouns for the proper adjective Doppler.
