    Complete question is The frequency of the fundamental of the guitar string is 320 Hz. At what speed c do waves move along that string? wavelength is 40 cm.

    Answer:

    128 m/s

    Explanation:

    In case where fundamental frequency is given, the speed with waves travel along the string can be calculated using the following formula:

    v = f (2L) where L is the length of the string (L = λ/2)

    ⇒v = f λ

    f = 320 Hz (given)

    λ = 40 cm = 0.40 m

    Substitute the values:

    ⇒ v = 320 Hz * 0.40 m = 128 m/s
