Final answer:
The given statement "The "dub" consists of two shots" is false. It is incorrect because a standing wave is formed by the superposition of two identical, in-phase waves traveling in opposite directions, resulting in a wave pattern with nodes and antinodes.
Step-by-step explanation:
The statement is false. A standing wave is the superposition of two identical waves that are in phase but propagating in opposite directions.
When these two waves interfere with each other, the result is a pattern of nodes, where the medium does not move, and antinodes, where the medium moves with maximum amplitude.
This is due to the constructive (at the antinodes) and destructive (at the nodes) interference between the waves.
For a standing wave to occur, the waves must have the same frequency and amplitude but travel in opposite directions along the same medium.
Hence, the statement is false.
