18. Waves & Sound

Given that figure 1 shows a snapshot graph at $t=0s$ of a $5.0\mathrm{Hz}$ wave traveling to the left, which of the following equations correctly represents the wave function $y(x,t)$?

In a diagram of a sound wave, if you observe $3$ complete cycles from crest to crest, how many wavelengths are present in the image?

Consider three wire-mass systems, each consisting of a wire of length $L$, but with different masses attached: System A has mass $m$, System B has mass $2m$, and System C has mass $3m$. All wires are under the same tension. Rank the systems according to the fundamental wavelength of the standing wave that can be formed on each wire, from largest to smallest.
