A sinusoidal wave is traveling on a string with a speed of 40 cm/s.The displacement of the particles of
the string at x = 10 cm is found to vary with time according to theequation
y = (5.0 cm) sin [1.0 â (4.0 s-1)t]. The linear density of thestring is 4.0 g/cm.
(a) What is the frequency of the wave?
(b) What is the wavelength of the wave?
(c) Write the general equation giving the transverse displacementof the particles of the string as a
function of position and time.
(d) Calculate the tension in the string.
