| The Doppler effect is a change in the frequency of sound waves caused by moving objects. |
| Basically the Doppler effect is that pitch increases the closer something gets to you, and it decreases the further away it gets. |
| Synth notes bob, bend and warble, producing a strange, droning, Doppler effect, whizzing past the listener like vehicles on a Tron superhighway. |
| The inverse Doppler effect is not something you can hear, but understanding it could one day lead to important advances in optics and communications equipment. |
| By analogy, the electromagnetic radiation emitted by a moving object also exhibits the Doppler effect. |
| This determination assumes the variation of the redshift is indeed a Doppler effect due to motion of the star. |
