JURPA 2025 Cover.
This study uses schlieren photography to visualize the interference patterns of ultrasonic sound waves in air. By capturing variations in a region’s refractive index, direct, real-time images of wave interactions are produced. Our system enhances the understanding of acoustic phenomena and demonstrates the feasibility of low-cost schlieren setups for educational and research applications.
