A sinusoidal wave is traveling on a string with speed 34.9 cm/s.The displacement of the particles of the string at x = 5.9cm is found to vary with time according to the equation
y = (3.9 cm) sin[1.2 - (7.1s-1)t].
The linear density of the string is 4.8 g/cm. What are(a) the frequency and (b) thewavelength of the wave? If the wave equation is of the form
y(x,t) = ym sin(kx -ωt),
what are (c) ym,(d) k, and (e)ω, and (f) the correct choice of sign infront of ω? (g) What is the tension inthe string?
