Shock wave from a Trombone Caught on Film

May 29, 2011 Leave a comment

The weak shock wave emanating from a trombone was captured on film and presented at the 161st Meeting of the Acoustical Society for America in Seattle.

The researchers used schlieren photography to capture the images. This method is able to image fluids through the changes in their refractive index and is used largely in aeronautical engineering to study air flow around airplanes.

It’s also wicked-cool :)
