What is the speed of the wave?

  1. Apr 13, 2009 #1
    1. A periodic longitudinal wave that has a frequency of 20.0 Hz travels along a coil spring. if the distance between successive compressions is 0.4m, what is the speed of the wave?

    2. v= wavelength times frequency

    3. v= wavelength times frequency
    = 0.4 * (20)
    = 8 m/s ------ I'm not sure if this is right.
