Imagine a world where sound becomes visible. In a room full of conversation, we would see soundwaves flowing from person to ...

Seen here, the waves combine into a square wave with it looking squarer as I add more and more signals that are multiples of the main frequency called harmonics. When building a square wave only ...

The diagram shows that when water waves are reflected their direction changes, but their wavelength and frequency remain unchanged. Refraction is the change in direction of a wave as it travels ...

The film explores the properties of sound waves in air, demonstrating that sound travels at approximately 1,100 feet per second and reflects similarly to light. Through experiments using echoes, beams ...
