Sound waves produced by very small sources diverge in the shape of a _____.

Explanation:
A very small source acts as a point source, radiating sound energy outward in all directions. In a two-dimensional diagram of the spreading rays, those rays fan out from the single point, forming a V-shaped pattern that shows divergence. In three dimensions, the wavefronts are expanding spheres, but a cross-sectional view still looks like rays diverging from a single point, hence the V shape. Larger or more directional sources wouldn’t produce this same divergent, point-source pattern, which is why the V shape is the best representation.
