DOPPLER SHIFT Meaning and
Definition
-
Doppler Shift refers to the change in frequency and wavelength of a wave, such as light or sound, as observed by an observer moving relative to the source of the wave. This phenomenon is caused by the relative motion between the source and the observer and affects the perceived pitch or frequency of sound waves or the color or frequency of light waves.
When there is a relative motion between the source and the observer, the wavelength and frequency of the wave change. If the source and the observer move towards each other, the waves become compressed, resulting in a higher frequency and shorter wavelength. This is known as the "blue shift" and is observed as an increase in pitch or the wavelength shifting towards the blue end of the spectrum in light waves. Conversely, if the source and the observer move away from each other, the waves become stretched, resulting in a lower frequency and longer wavelength. This is known as the "red shift" and is observed as a decrease in pitch or the wavelength shifting towards the red end of the spectrum in light waves.
Doppler Shift has significant applications in various fields, including astronomy, meteorology, and medical imaging. It allows scientists to determine the relative motion of celestial objects, analyze the velocity and direction of moving weather systems, and measure blood flow in medical imaging. Overall, Doppler Shift is a fundamental concept that describes the change in frequency and wavelength of waves due to the relative motion between the source and the observer.

Etymology of DOPPLER SHIFT
The word "Doppler Shift" is named after Christian Doppler, an Austrian physicist and mathematician who first described the phenomenon of the effect in 1842. The term "Doppler" comes from his last name, and "shift" refers to the change in frequency or wavelength of a wave caused by the relative motion between the source of the wave and the observer. Thus, "Doppler Shift" refers to the change in frequency or wavelength of a wave due to the motion of either the source or the observer (or both) along the line of sight. The concept of Doppler Shift is widely used in various fields, including astronomy, acoustics, radar, and medical imaging.
