Sound Waves in Air (1961)

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 of sound, and various setups, the film illustrates the principles of reflection, refraction, interference, and standing waves. It confirms that sound behaves as a wave phenomenon, with characteristics such as bending around obstacles and creating interference patterns. The relationship between speed, frequency, and wavelength is also established, showcasing sound's predictable behavior in accordance with wave theory.
