This 9-minute video uses an oscilloscope to demonstrate how the loudness of a sound is related to its wave amplitude and how pitch is related to frequency. The author explicitly clarifies a concept that is commonly misunderstood: although the wave pattern produced by the oscilloscope looks like a transverse wave, sound is NOT transverse-it is longitudinal. The instrument detects compressions (high pressure areas) and rarefactions (low pressure areas) in the longitudinal wave and translates them into an electrical signal to produce a graph of Distance Vs. Time. The video then explains how the human ear is able to hear different frequencies of sound, which we perceive as varying pitches. Professional scripting and animation serve to provide a deeper learning experience than traditional lecture demonstrations.
Editor's Note: This video is part of a larger collection of resources produced by Mindset Learn, a nonprofit organization. Each video was created under the supervision of the University of Johannesburg.
