Physics

Vibration from a 620 Hz tuning fork sets up standing waves on astring clamped at both ends (one of which you may take as x=0). Thetravelling wave speed on this string is 440 m/s. The standing wavehas four anti-nodes and an amplitude of 2.0 mm.

(a) What is the length of the string?
___ m

(b) Write an equation for the transverse displacement of the stringas 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 thisstanding wave?
___ m
