A rope has one end tied to a vertical support. You hold the other end so that the rope is horizontal. If you move the end of the rope back and forth with a frequency of 4 Hz, the transverse wave you produce has a wavelength of 0.5 m. What is the speed of the wave in the rope?

    2 m/s.

    Explanation:

    The relationship between frequency, wavelength and speed of a wave is given as:

    v = λ * f

    where,

    v is the speed of the wave

    λ is the wavelength

    f is the frequency

    Given:

    f = 4 Hz

    λ = 0.5 m

    v = (0.5 * 4)

    = 2 m/s.
