Such a common experience in our everyday lives, the Doppler Effect has proved to be a major factor in demonstrating the existence of an ever-expanding universe. Simply put, the effect occurs when ...

By taking note of something called the Doppler effect and making close observations of the light from stars, we're able to tell not only if those stars are moving to or away from us but how fast ...

The frequency of the returning signal typically changes based upon the motion of the raindrops (or bugs, dust, etc.). This Doppler effect was named after the Austrian physicist, Christian Doppler ...
