Homework Help: Sinusoidal Waves and Intensity

  1. Feb 7, 2008 #1
    1. The problem statement, all variables and given/known data

    For this assignment, its on travelling waves. If you'll have a look at it, you'll see I've been unable to solve questions questions 20-23 and question 33. Can you please help me solve them? Also can you please verify if I've done questions 25- 31 correctly?


    2. Relevant equations

    Y(x,t) = Asin(kx-wt+theta)
    Y(x,t-0) = Asin(theta)


    3. The attempt at a solution
