Can someone explain to me what i did wrong on this quiz? waves

  1. Apr 5, 2006 #1
    hello everyone. I'm studying for the exam now and I understand if a wave is moving in the negative x direction to the left, the value infront of the x should be positve. But you see where he took off -1/2, because i wrote down m/s? Do you know why? its v^2, i thought that just means take the value of v, square it. should it have been m^2/s^2?

    Yes, it should have been m^2/s^2. Note that the d^2y/dt^2 is in m/s^2 and the d^2y/dx^2 is in 1/m.
