The vertical displacement of a string is given by y(x,t) = (6.00 mm) cos[(3.25 m^-1)x - (7.22 s^-1)t]. What is the amplitude of the wave? A) 6.00 mm B) 12.0 mm C) 3.00 mm D) 2.00 mm E) None of the other choices is correct.

Question

Quizplus · Accepted Answer

The amplitude of a wave is the maximum displacement from the equilibrium position. In this case, the maximum displacement is 6.00 mm, which is the amplitude of the wave. Therefore, the answer is choice A.
