Just in time for the Detroit Grand Prix, the Michigan Science Center demonstrates how the doppler effect causes the sound of speeding cars passing by.

As the car recedes, the reverse effect stretches the wave, making it sound lower. The changing pitch of the note is called the Doppler effect. It is found in many contexts and is remarkably useful.

So long as skiing and a trombone is involved, there is no such thing as a dull science lesson. For all of us who fell asleep during science class (I see you), the Doppler effect is the change in ...

In the melee, with all of us asking and no one answering, she said, “It’s the Doppler effect of questions.” I smiled because I immediately knew exactly what she meant. The Doppler effect is ...

Redshift, blueshift and the Doppler effect The concept of redshift and blueshift is closely related to the Doppler effect — which is an apparent shift in soundwave frequency for observers ...

The Doppler effect, which detects energy pulses, was discovered by Austrian physicist Christian Doppler and named after him. Doppler radar is “a remote sensing tool, which basically means it ...

Controversial research suggests the Big Bang may be a myth due to its reliance on the Doppler effect theory. This idea says the universe is neither expanding, nor contracting; instead it is steady ...

This is thanks to what's called the Doppler effect—the way speed affects the length of waves, such as sound or light. When light changes color due to speed, we call it redshift or blueshift ...
