Unlike linear sequential arrays the sound beams transmitted from a convex array _________ to each other.

Unlike linear sequential arrays the sound beams transmitted from a convex array _________ to each other.

• A. are parallel
• B. are not parallel
• C. intersect
• D. diverge

Answer: (B)

Beams from a convex array diverge because the curved geometry makes each element emit at a slightly different angle, so the paths spread apart as they travel. In a linear sequential array, the geometry and timing align the beams so they travel in the same direction, making them parallel. So, for a convex array, the beams are not parallel—they diverge.
