This is called the Doppler shift... I think.

YoursTruly · Answer

And Doppler means?

Bob · Answer

It's the surname of the guy that created the effect. .-.

Oh. XD Woops. >.> You know how when you stare at something, and there's a light behind it, there's either a yellow or blue outline around the object?

Anyways... when an object is moving closer towards you, it has high frequency. But when it moves farther away, there's lower frequency...

Bob · Answer

Farther to the right is high frequency (an object moving towards you.)

Farther to the left is low frequency (an object moving away from you.)
