Question

1. use the illustration above. what parts of the wave are labeled x and y?

x represents the rarefactions; y represents the compressions.
x represents the compressions; y represents the rarefactions.
x represents the compressions; y represents the wavelength.

Explanation:

Step1: Recall properties of longitudinal waves

In a longitudinal wave, compressions are regions where particles are close together, and rarefactions are regions where particles are spread apart. The wavelength is the distance between two consecutive compressions or two consecutive rarefactions.

Step2: Analyze the labels

Looking at the diagram, \(X\) is the distance between two consecutive compressions (or rarefactions), so \(X\) is the wavelength. \(Y\) is a region where particles are spread apart, so \(Y\) is a rarefaction.

Answer:

\(X\) represents the wavelength; \(Y\) represents the rarefactions.
