Sound
Sound
This article explores the nature of sound, from the microscopic behavior of air particles to the macroscopic phenomena of pressure waves and their interaction with the environment. It uses interactive demonstrations to illustrate key concepts such as frequency, amplitude, phase, and the Doppler effect.
Note
the interactive medium is fascinating as it straddles the difficult line between learning and entertainment.
the essay takes on a difficult subject and does a great job given the constraints of time. it's strength is in the showcase of web APIs and manipulating sound.
ultimately, i think quizzes, more chapters and deeper open ended experiences would be needed to solidify what is being taught. yet, for the space it takes, so much definitely gets accomplished.
i look forward to reading their many other takes on subjects, next up: bikes!
