The maximum transverse displacement of the string from its equilibrium position is 5 cm.
At a fixed instant in time, the distance between two points where the string has zero displacement from its equilibrium position is 40.
At a first position along the string, you observe that the string has zero displacement from its equilibrium position. and then it starts to be displaced. After 0.1 sec. elapses, you again observe that the string has zero displacement from its equilibrium position. (at that point along the string)
From the data above, plug in numerical values into:
y(x,t)=Acos[2pi((x/lambda)-(t/T)
A-amplitude
x-position
lambda- wavelength
t- time
T- Period
