Question regarding wave motion

  1. Jan 29, 2005 #1
    A stationary wave is represented by

    y= 0.3cos 12x sin t

    (a)What is phase difference between the points where x =0.1m and x=0.5m ?

    Can anybody give suggestion for me to solve this question ?I have think for this question for a long time.Thanks for anybody that spend sometime on this question.

    All you care about is the spatial variation, so rewrite your equation like this:
    y= A cos 12x

    Now what "phase angle" (in radians) is obtained at x = 0.1m and x = 0.5m?
