The doppler effect翻译
WebThe Doppler effect occurs for all kinds of waves. It happens when either the source of the waves or the receiver of the waves is moving. The picture shows that the sound waves get compressed as the car moves toward you, creating a higher pitch sound. As the car moves away, the sound waves get spread out and you hear a lower sound.

WebA Doppler ultrasound is an imaging test that uses sound waves to show blood moving through blood vessels. A regular ultrasound also uses sound waves to create images of structures inside the body, but it can't show blood flow. Doppler ultrasound works by measuring sound waves that are reflected from moving objects, such as red blood cells.

The effects are most commonly studied in sound waves and light waves. It is noticeable when a train or a car passes by while emitting a horn sound.

That summer, my younger brother and I biked a mile from our house to the railroad tracks every day, where we’d built a hidden fort between the boulders and slabs of rock, making a roof out of leafy branches.

WebMar 17, 2024 · I told her that: Doppler effect is about alteration of the perceived frequency of a signal produced by the relative movement between transmitter and receiver. The quoted video is about relativity, which is a "deeper" effect. Maybe Doppler effect can be understood as the effect of relativity on a (slow) wave phenomena.
