# Wave parameters

1) A transverse traveling wave on a cord is represented by D = 0.48 sin (5.6x +84t) where D and x are in meters and t in seconds. For this wave determine (a) the wavelength (b) the frequency (c) velocity (magnitude and direction) (d) amplitude and (e) maximum and minimum speeds of particles of the cord.

#### Solution Preview

The wave equation is given by

D = A sin (kx +w t)

Where

A= amplitude = 0.48 m ( in this example)

k = wave number = 2 pi / lambda = 5.6 ( in this example)

w = 2 pi f = 84 ( in this example)

(a) the wavelength lambda

k = 2 pi / lambda = 5.6

therefore lambda = ...

#### Solution Summary

The solution calculates (a) the wavelength (b) the frequency (c) velocity (magnitude and direction) (d) amplitude and (e) maximum and minimum speeds of particles of the cord
