    Answer:

    f = 4.95\ hz

    Explanation:

    Given,

    Student create wave of three loop on a slinky 3.75 m.

    number of oscillations= 20

    Time, t = 6.73 s

    Frequency = \dfrac{20}{6.73}

                      = 2.97 Hz

    We need to find frequency when 5 loops is created.

    f = \dfrac{5}{3} \times 2.97

    f = 4.95\ hz
