A standing wave on a 0.8 m string is described by the relation y = 0.02 sin 5nx cos 100 nt Si units.
(a) What are the amplitude, frequency, and wavelength?
(b) Draw the standing wave pattern. Which harmonic is this? (Counting the lowest frequency as 1, what is the number of this one?)
(c) The mass of the string is 0.008 kg. What is the tension in the string?
The middle C string on a piano is under a tension of 744 N. The period and wavelength of a wave on this string are 3.82 10-3 s and 1.26 m, respectively. Find the linear density of the string.
