Idea
Schlieren Imaging is a technique proposed by the German physicist August Toepler in 1864 to study supersonic motion. We are using this tool to see the ultrasound wave and its propagation. The sound wave is propagation by the vibration of the air. When the air vibrates, the air will be either denser or less.
