Simple Standing Wave
This animation shows a standing wave resulting from the superposition of two plane waves traveling opposite directions.
The left side of the figure shows a representation of the molecular distribution. The darker areas represent areas where the density is greater indicating a compression. Midway between the compressions are regions of lower density indicating rarefactions.
The right side of the figure shows a plot of the resulting acoustic pressure or acoustic velocity profile.
