1. If
y(x,t) = (8.4 mm) sin[kx + (770 rad/s)t
+ φ]
describes a wave traveling along a string, how much time does any
given point on the string take to move between displacements
y = +1.2 mm and y = -1.2 mm?
2.A sinusoidal wave travels along a string. The time for a particular point to move from maximum displacement to zero is 0.25 s. What are the (a) period and (b) frequency? (c) The wavelength is 2.0 m; what is the wave speed?
3.The equation of a transverse wave on a string is
y = (4.1 mm) sin[(13 m-1)x + (450
s-1)t]
The tension in the string is 28 N. (a) What is the
wave speed? (b) Find the linear density of this
string.
