Doppler effect | Definition, Example, & Facts | Britannica
Doppler effect, the apparent difference between the frequency at which sound or light waves leave a source and that at which they reach an observer, caused by relative motion of the observer and the wave source. It was first described (1842) by the Austrian physicist Christian Doppler.
17.8: The Doppler Effect - Physics LibreTexts
The Doppler effect is an alteration in the observed frequency of a sound due to motion of either the source or the observer. The actual change in frequency is called the Doppler shift.

Doppler Effect - NASA
The sound that our ear detects will change in pitch as the object passes. This change in pitch is called a doppler effect. There are equations that describe the doppler effect. As the moving source approaches our ear, the wavelength is shorter, the frequency is higher and we hear a higher pitch.

Doppler Effect Explained - BYJU'S
Doppler Effect Explained Doppler effect is an important phenomenon in various scientific disciplines, including planetary science. The Doppler effect or the Doppler shift describes the changes in the frequency of any sound or light wave produced by a moving source with respect to an observer. Doppler effect in physics is defined as the increase (or decrease) in the frequency of sound, light ...
