Physics term for a shift in position, frequency, or other measurable quantity. Often used in compounds like 赤方偏移 (redshift) and ドップラー偏移 (Doppler shift).
By observing the shift of light, we can understand the motion of distant galaxies.
ドップラー偏移は、音源や光源が動くときに生じる。
The Doppler shift occurs when a sound source or light source moves.
