Homework Help: Sonar Wave Problem

  1. Mar 9, 2014 #1
    1. The wave speed of a longitudinal wave in steel is 5941 m/s. The Speed of a longitudinal wave in water is 1482 m/s. If a bar of steel is struck with a hammer and a wave with wavelength 10.24 m travels through the steel into water, what will be the wavelength of the wave in water?

    2. Relevant equations

    I just really don't know how to go through a problem like this. If someone could help me piece it together step-by-step, I would greatly appreciate it.

    Try using this formula [itex]: v=\lambda \cdot f [/itex]
    Where [itex] v [/itex] is the speed of the wave, [itex] \lambda [/itex] is the wave length and [itex] f [/itex] is the frequency.

    Hint: The frequency is always the same in this case.
