## compressionrarefaction.jpg

The image is a diagram illustrating sound waves, specifically focusing on pressure variations over time. The title of this figure is "Figure 1," which suggests it might be part of an educational material.

At the top of the diagram, there's a horizontal line labeled as "Pressure" with arrows pointing upwards and downwards to indicate changes in air pressure. Below this line are two sets of wavy lines representing sound waves. These waves have peaks (condensations) where the air is more compressed, and troughs (rarefactions) where it is less dense.

The diagram includes labels for key parts of a wave:
- "wavelength" is marked between two consecutive crests or troughs.
- "Distance" is labeled at the bottom center, indicating the space between condensations and rarefactions along the horizontal axis.

Below these waves are dotted representations showing how air molecules move during sound propagation. The dots cluster more densely in areas of condensation (where the air pressure is higher), and spread out more thinly in areas of rarefaction (where the air pressure is lower).

There are no people or characters depicted in this image, only scientific illustrations to explain a concept related to physics.
