Homework Help: [Q] - Wave moving along a string

  1. Mar 23, 2009 #1
    1. The problem statement, all variables and given/known data

    y(x,t) = (6.0 mm) sin(kx + (600rads/s)t + phi)

    That is the description of a wave moving along a string.

    How much time does any given point on the string take to move between y = 2 mm and y = -2 mm?

    2. Relevant equations

    I don't know any I am sorry.

    But, I know :

    Angular Frequency = 600rads/s

    Amplitude = 6mm

    3. The attempt at a solution

    I don't know any formula with t(time) in it.

    If anyone could help that would be great

    You say, "I don't know any formula with t(time) in it."

    What about the given expression for y(x,t), doesn't that have a t in it?

    Yes, but can you show me some working, I don't get it >.<

    ".... show you some working." I don't get it as to what you mean.

    I don't understand the wave equation.

    Can you partially solve the problem so that I am able to follow you and see if I am able to solve the problem and understand what you have done.

    A little explanation along with your working, the partially solved problem, would be great.
