THE DOPPLER EFFECT Meaning and
Definition
-
The Doppler effect refers to the phenomenon observed when there is a relative motion between a source of waves or vibrations and an observer. It describes the change in frequency or wavelength of the waves as perceived by the observer due to this relative motion.
When the source of waves and the observer move closer together, the observer experiences an increase in frequency or pitch of the waves. Conversely, when they move apart, the observer perceives a decrease in frequency or pitch. This shift in frequency is experienced whether the waves are sound waves, light waves, or any other type of wave.
The Doppler effect is explained by the change in the distance between the source and the observer during the propagation of the waves. As the distance decreases, the observer experiences an increase in the number of waves crossing a fixed point in a given time, resulting in a higher frequency. Conversely, as the distance increases, there is a decrease in the number of waves reaching the observer, resulting in a lower frequency.
This phenomenon has various real-life applications. For instance, it is utilized in radar systems to measure the velocities of moving objects by using the frequency shift of the radar waves reflected off them. In astronomy, the Doppler effect helps determine the motion of celestial objects such as stars and galaxies based on the shift in the frequency of light emitted or absorbed by them. Thus, the Doppler effect plays a significant role in understanding and interpreting many phenomena related to waves and vibrations in different fields of science and technology.
