Periodic Motion and Mechanical Waves (4A) Practice Test

A researcher compares two sinusoidal waves traveling in the same direction through the same fluid: Wave 1 and Wave 2 have the same frequency, but Wave 2 has a larger amplitude. Which conclusion is most consistent with mechanical wave behavior in a linear medium?

A damped spring–mass system is used to model soft-tissue vibration after an impulse. Compared with an otherwise identical system with less damping, the more heavily damped system is observed to have a smaller oscillation amplitude after the same initial displacement. Which statement is most consistent with periodic motion in damped systems?
