DOPPLER EFFECT Meaning and
Definition
-
The Doppler Effect is a scientific phenomenon that describes the change in frequency or wavelength of a wave, such as sound or light, as it is perceived by an observer moving relative to the source of the wave. When the source of the wave and the observer are moving towards each other, the frequency of the wave appears higher, thus resulting in a higher pitch for sound waves. Conversely, when the source and the observer are moving away from each other, the frequency appears lower, resulting in a lower pitch for sound waves. This effect is commonly experienced when a moving vehicle passes by, with the sound of the engine appearing to change pitch as it approaches and then moves away.
The Doppler Effect is not only applicable to sound waves but also to other forms of waves, such as light waves. In the case of light waves, the observed color of an object can also change depending on the relative motion between the source and the observer. This effect can be seen in daily life with phenomena like redshifting and blueshifting, where the light emitted by sources moving away from us appears to be redder, while sources moving towards us appear to be bluer.
The Doppler Effect is an important concept in various scientific disciplines, including astronomy, meteorology, and acoustics. Its understanding allows scientists to gather information about the motion and velocity of objects, as well as gain insights into the expansion of the universe.

Etymology of DOPPLER EFFECT
The term "Doppler Effect" is named after the Austrian physicist Christian Doppler, who first described the phenomenon in 1842. The word "Doppler" is derived from his surname, while "Effect" refers to the alteration or change in a particular phenomenon caused by the Doppler shift. The Doppler Effect refers to the change in frequency or wavelength of a wave (such as sound or light) as perceived by an observer when there is relative motion between the source of the wave and the observer.
