Light Pipe Sculpture: internal reflection constrains most of the laser light to propagate along the bent acrylic rod- the physics of fiber optics. This abstract sculpture was created by applying a heat gun to a 3/8” diameter acrylic rod. The laser pointer used here is blue at a wavelength of 445nm. ➡️ Follow the link in my profile for info on where to get a light pipe demo like this and other amazing items featured here on @physicsfun #optics #lightpipe #internalreflection #refraction #refection
