Fascinating! One of the questions it suggests to me is: if it’s useful to make sound visible in order to learn more about sound, why does it make any less sense to make light audible in order to learn more about light? The only such experiments that come to mind are the ones in recent years involving turning electromagnetic radiation from outer space into “sound.” But those efforts are too often characterized in the press as if EMR were sound, which of course it isn’t.
I’m always grappling with the ways we perceive light and sound differently, and trying to understand why sound so often gets subordinated. There might be a clue here, in our inclination to assume we can learn about sound via light, but not light via sound.
