The Doppler effect is one of the most popular methods for the analysis of the dependence of the investigated object to the distance from the source. In physics, the term "Doppler effect" most often means a change in the frequency of the electromagnetic (or acoustic) wave, when the source is moving at a speed relative to the observer. Such a method is used in medicine for monitoring the speed of blood flow in blood vessels where there is a suspicion of clogging. In physics this effect ups tracking uk is most common in astronomy to determine the positions of stars in galaxies. When the light source and the observer is near, the wavelength of the spectral lines decreases, the change of wavelength is negative and observed blue shift of the lines of the spectrum of the source. When the source and the observer are moving away, the wavelength increases, then it is a positive change and observed redshift. The Doppler effect is used in radar meteriologiya. By moving particles and precipitation changes the wavelength of the radar pulse, so that the length of the received wave by the receiver to that of the transmitted pulse is different. By Doppler radar on Climate wavelength can determine the speed of the drop relative wind, ie measured wind speed. It is also meant to monitor and nuclear physics. Makes one such experience in which we put a source of alpha particles to the detector and the spectrum of an emptied ups tracking uk into the detector helium nuclei. Then, the source is placed at another distance and again raise the spectrum of the same source. Thus, by comparing the two spectra will noticeable shift in the lines. This shift is due to the Doppler effect. This entry was posted ups tracking uk in General Physics, Articles and tagged Doppler Doppler effect Doppler applications by diana. Bookmark the permalink.
