Abstract

Since "Kundt's experiment", it has been well known that an acoustic stationary wave in an air column regularly places particles of powdered wood or foamed polystyrene at each loop of the wave in parallel stripes, but no one has never revealed why it makes the particles form a row in stripes. Although the movement of a medium on a stationary wave seems to play a critical role in this phenomenon, there was no visual material filming the clear images of the state of a stationary wave in an air column. The present study has a purpose to investigate and visualize the behavior of a medium on a stationary wave. The procedure of the study was as follows: While an acoustic stationary wave was being generated in an air column filled with cigarette smoke, the micro particles of the smoke were visualized through a laser scanning visualization system and filmed with a high-definition video camera.
