Welcome to the third episode of "The World Through Sound," an online series from Acoustics Today that demonstrates how gaining a basic understanding of acoustics may alter the way you perceive the world. The last time, we talked about frequency and how, for acoustic waves, the link between frequency and time might assist explain the Uncertainty Principle of quantum mechanics. In this article, we will discuss wavelength and the significance of scale in dealing with physics by combining the ideas of the previous two topics on sound speed and frequency.
