Determine the number of nodal line present

    1. The problem statement, all variables and given/known data
    Using a swimming pool, two students decide to test the water by setting up an interference pattern at one end of the 50 m pool. They sit 2.0 m apart and create waves by tapping their right foot, in phase with each other, onto the water at a frequency of 1.0 Hz. The speed of the waves is measured to be 0.60 m/s. The teacher is standing at the other end of the pool watching the pattern that is created and decides to count the number of nodal lines present. What is the total number of nodal lines present in the pattern generated?
    i do not know the calculation for calculating the number of nodal line but i have found the wavelength


    2. Relevant equations



    3. The attempt at a solution

    Did you calculate the wavelength with the V = Frequency x Lambda?
