A Thin Taut String Is Fixed at Both Ends and Stretched

question 49

Essay

A thin taut string is fixed at both ends and stretched along the horizontal x-axis with its left end at x = 0.It is vibrating in its third OVERTONE,and the equation for the vertical displacement of any point on the string is y(x,t)= (1.22 cm)sin[(14.4 m^-1)x] cos[(166 rad/s)t].
(a)What are the frequency and wavelength of the fundamental mode of this string?
(b)How long is the string?
(c)How fast do waves travel on this string?
