Homework Help: Sinusoidal waves

  1. Dec 1, 2006 #1
    A sinusoidal wave of frequency 500 Hz has a speed of 350 m/s.
    (a) How far apart are two points that differ in phase by Pi/3 rad?

    I was thinking that I need to use the equation y= Asin(kx-wt+pi/3)

    I found the wavelength=0.70m

    used this to find k=8.98

    solved for w by converting the frequency to the period and using w=2pi/T to get w=3141 but I don't have amplitude.

    I figured after plugging everything in and solving for x gives me the distnace apart. Is this the right approach?

    What is the phase difference between two points that are a whole wavelength apart?
