Can we manipulate sound waves using the same principles as light?
Just as glass bends light, different gases can bend sound. This video explores the physics of refraction and how varying the medium through which a wave travels allows us to create a lens for sound.
The fundamental principle behind both optical and acoustic lenses is refraction. This phenomenon occurs when a wave changes direction because it passes between mediums with different wave speeds. By utilizing different gases, it becomes possible to engineer a system that redirects sound waves, effectively mimicking the behavior of a traditional light lens.
