How to Take Pictures of Sound Waves with $9 and your Camera
Share:
A couple of months ago, I wrote a post going over Schilieron Flow Visualization, a method used to detect and visualize waves emitted from sound. NPR gave us a detailed and incredibly informative look into how it was all done.
Now, it looks like there’s a way to capture those waves through a lens yourself. A user on Instructables named jlansey recently put up a tutorial going over how you can make your own setup on a $9 budget (…assuming you already have a camera, of course).
What are you going to have to gather? The tutorial requires you to go out and buy a pair of page magnifiers; find yourself a light source – LED, preferably – and the rest are things you’ll find in your house without fail. Check out the full tutorial here.
I remember reading about this back when I was writing on it, and really thought it was a bummer how expensive it looked. Now that we actually have a viable and affordable way to achieve the Schilieron Flow Visualization effect, I think we should take advantage of it. Heads up, physics teachers.
