Travelling waves equation

  1. Jun 9, 2012 #1
    (a) The displacements of two travelling waves are given by:

    D1(x,t) = A sin[kx +ωt +φ]

    and

    D2 (x,t) = A sin[kx −ωt +φ] where A=0.01m, k=5rad.m−1,ω=200rad.s−1 andφ=π3rad

    (i) Use the appropriate trigonometric identity to find the displacement resulting from the superposition of these two waves.

    (ii) Is the wave resulting from this superposition a travelling wave? Briefly explain your answer.

    (iii) Find a value for the separation between adjacent maxima (antinodes) in the resultant wave.

    thanks guys

    you've got to try it for yourself first. read through the first question, and think of what they are asking you to do.
