Nous sommes sur la même longueur d’onde.

We are on the same wavelength.
Very straightforward today, don’t you think? Except that, while waves do move forward, I don’t think they move straight. If a wave were a straight line, it wouldn’t be a wave.
Have you ever stopped to think about how we listen to the radio? I’m pretty sure we all got over the tiny-man-in-a-box theory a long time ago. And we know about pushing buttons or turning dials. But what does that accomplish, other than shutting down the most annoying song on the planet?
For those who never studied physics, there’s a nice neat explanation in Wikipedia, here. It’s in English and it’s fairly easy to understand, or at least to get the gist of. And it has a pretty diagram of sound waves bending around the world.
Since frequency and wavelength have a constant relationship, talking about one inevitably implies the other. If you and I are on the same wavelength, sur la même longueur d’onde, we are resonating in sync with each other. We understand each other, we are in harmony. Which means that we can actually hear each other.
