Vibration from a 475 Hz tuning fork sets up standing waves on a string clamped at both ends (one of which you may take as x=0). The travelling wave speed on this string is 380 m/s. The standing wave has four anti-nodes and an amplitude of 4.0 mm.
(a) What is the length of the string?
(b) Write an equation for the transverse displacement of the string as a function of position and time:
y(x,t) = (___mm) sin (___m^-1 x)cos(___s^-1 t)
(c) What is the wavelength of the travelling waves that form this standing wave?
