Quizplus · Accepted Answer

The transverse speed of a wave is directly proportional to its amplitude. In this case, the amplitude of each wave is proportional to its coefficient in the equation. Therefore, we can rank the waves by comparing their coefficients. From largest to smallest, the coefficients are: 3, 2, and 1. Therefore, the correct order is 2, 1, 3, or choice C.
