1. Doppler

   The Doppler effect or Doppler shift (or simply Doppler, when in context) is the change in frequency of a wave in relation to an observer who is moving relative to the wave source. It is named after the Austrian physicist Christian Doppler, who described the phenomenon in 1842. A common example of Doppler shift is the change of pitch heard when a vehicle sounding a horn approaches and recedes from an observer. Compared to the emitted frequency, the received frequency is higher during the approach, identical at the instant of passing by, and lower during the recession.The reason for the Doppler effect is that when the source of the waves is moving towards the observer, each successive wave crest is emitted from a position closer to the observer than the crest of the previous wave. Therefore, each wave takes slightly less time to reach the observer than the previous wave. Hence, the time between the arrivals of successive wave crests at the observer is reduced, causing an increase in the frequency. While they are traveling, the distance between successive wave fronts is reduced, so the waves "bunch together". Conversely, if the source of waves is moving away from the observer, each wave is emitted from a position farther from the observer than the previous wave, so the arrival time between successive waves is increased, reducing the frequency. The distance between successive wave fronts is then increased, so the waves "spread out". For waves that propagate in a medium, such as sound waves, the velocity of the observer and of the source are relative to the medium in which the waves are transmitted. The total Doppler effect may therefore result from motion of the source, motion of the observer, or motion of the medium. Each of these effects is analyzed separately. For waves which do not require a medium, such as electromagnetic waves or gravitational waves, only the relative difference in velocity between the observer and the source needs to be considered. When this relative velocity is not negligible compared to the speed of light, a more complicated relativistic Doppler effect arises.

1. doppler

   The Doppler effect or Doppler shift is a change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. It's named after the Austrian physicist Christian Doppler, who first proposed the concept in 1842. The Doppler effect is commonly heard when a vehicle sounding a siren or horn approaches, passes, and recedes from an observer. The received frequency is higher (compared to the emitted frequency) during the approach, identical at the instant of passing by, and lower during the recession.

1. Doppler

   Doppler is a lunar impact crater named for Christian Doppler that is located at the southern edge of the walled plain Korolev, on the far side of the Moon. To the east are the craters Das and Galois. Farther to the southwest of Doppler is Mohorovičić. The rim of Doppler has a somewhat polygonal form, and a smaller crater is joined with the inner side of the northeast wall. The interior of Doppler is rough and irregular, with some terracing of the worn outer walls, and a complex of central hills to the north of the midpoint. The crater Doppler B lies within the northern rim, and occupies a portion of the northern floor. A small, crater-formed valley runs to the southeast across the floor of Doppler from the rim of Doppler B.
