# traveling wave equation obtain much information about the wave.

One end of a long wire under tension is moved up and down sending a wave along it. Assume the wire lies along an x axis with the moving end at the origin. The equation giving displacement y, in meters, of points on the wave is:

(1) y= (.06 m) sin (5 x - 25 t)

a. From given constants, calculate the value and units of the quantities called for below:

angular frequency w, period T, wave number k, wavelength L,

wave speed c, partial derivative dy/dx at t= .17 sec, and the partial derivative dy/dt at x= 2.2 m.

b. Find the displacement of a point which is 2.0 m from the origin, at time t=.17 sec. .

c. For a point which is at x1= 2.4 m from the origin, write y(x1, t) with numbers and units for constants, for the SHM of that point, and find the maximum velocity of that point.
