## Homework Statement

The displacement function for a string carrying a transverse wave is

y(x, t) = 2.0mm*sin(20*x/m − 600*t/s)

Determine the amplitude, frequency, velocity and wavelength of the wave. Determine the maximum transverse speed

of any point on the string.

## Homework Equations

v = (T/mew)^1/2

freq = w/(2*pi)

## The Attempt at a Solution

amplitude is pretty easy,

**amp = 2.0**

frequency is pretty simple also by the equation i have gotten above by some substitution,

**freq = 95.4**

i have found the equation for the speed of a wave above, but lack mew(the density of the string). is there any other way to go about getting the speed?
