So find the smallest number for which t increases by that amount..In summary, the conversation discusses a sinusoidal wave traveling on a string with a speed of 10.00 cm/s. The displacement of the particles at x = 20 cm is described by y = (5.0 cm) sin[16.0 - (8.0 s-1)t]. The frequency of the wave is represented by s-1 and the wavelength is measured in cm. The general equation for the transverse displacement of the particles can be given as y(x,t) = (5.0 cm) sin[( cm-1)x - ( s-1)t]. To calculate the tension in the string, one must find the period of the wave

A sinusoidal wave is traveling on a string with speed 10.00 cm/s. The displacement of the particles of the string at x = 20 cm is found to vary with time according to the equation y = (5.0 cm) sin[16.0 - (8.0 s-1)t]. The linear density of the string is 7.0 g/cm.
(a) What is the frequency of the wave?
s-1
(b) What is the wavelength of the wave?
cm

(c) Give the general equation giving the transverse displacement of the particles of the string as a function of position and time.
y(x,t) = (5.0 cm) sin[( cm-1)x - ( s-1)t]

(d) Calculate the tension in the string.
