The Physics of Sound Waves: Pitch, Amplitude, and Frequency

Miacademy & MiaPrep Learning Channel

This educational video provides a comprehensive introduction to the physics of sound waves, starting with an engaging demonstration of how helium changes a person's voice. The narrator breaks down the fundamental mechanics of sound, explaining how vibrating objects like strings and speakers create compressions and rarefactions in the air. Through clear animations, the video illustrates the difference between longitudinal and transverse waves and defines key wave properties including wavelength, amplitude, and frequency.
