###### Question details

The tension in a string is 13.8 N, and its linear density is 1.05 kg/m. A wave on the string travels toward the -x direction; it has an amplitude of 3.17 cm and a frequency of 11.7 Hz. What are the (a) speed and (b) wavelength (in terms of m) of the wave? (c) Write down a mathematical expression (like Equation 16.3 or 16.4) for the wave, substituting numbers for the variables A, f, and λ.
