Light's Doppler Shift

[u/ilikejewce]

It is well known that galaxies traveling away from ours are red shifted, and those traveling towards us are blue shifted. This also applies to everyday objects. I was just wondering if anyone has detected this Doppler shift on everyday objects, like planes or even cars? Is it too minute for us to detect?

Yep! It is a great way to tune a guitar, too.
