- This is what's known as the Doppler effect.
這就是所謂的多普勒效應。

- This is called the Doppler effect, the change in a wave's frequency depending on if the molecule is moving closer to, or farther away from the observer.
這被稱為多普勒效應，即一個波的頻率變化取決於分子是在靠近還是遠離觀察者。

- You see, there is a sense in which it's not all that different from the Doppler effect, where relative movement corresponds to shifts in frequency.
你看，從某種意義上說，這與多普勒效應並沒有什麼不同，在多普勒效應中，相對運動對應著頻率的移動。
