A simple harmonic wave described by the equation y(t)= 0.54 cos(3.1x - 2.3t)reflects from both ends of a string that is clamped at each end,resulting in a standing wave that is the sum of y(t)and its reflection.What is the amplitude of the standing wave at x = 0.22 m? The quantities x and y are in meters,and t is in seconds.
A)0.84 m
B)0.57 m
C)0.67 m
D)0.77 m
