The video explores sound wave interference using a classroom experiment with two speakers. It demonstrates how sound waves can interfere constructively, resulting in louder sounds, or destructively, leading to silence. By adjusting the wavelength, the interference pattern changes, affecting the distribution of loud and quiet zones. The video highlights the significance of wave interference in everyday experiences.
