The sounds of the ocean are so relaxing… the waves crashing on the sand, the gentle roar of the surf. And if you pick up a big seashell and put it to your ear, you can almost hear the ocean there too! One of our listeners wanted to know why, so we asked physicist Steve Errede to help us catch that wave. Do you have a great question for Moment of Um?
