    The speed of the wave is 18\frac{m}{s}.

    Explanation:

    Given : FREQUENCY (F) = 6Hz

                 WAVELENGTH(λ) = 3m

    If a wave has frequency, f, of 6 Hz, its period, T, is \frac{1}{6}  s. The wavelength,  λ
    , is 3 meters. That means that in the time of one period, the wave travels 3 m.

    That means that in the time of one period, the wave travels 3 m.

    In General ,

    speed =\frac{distance}{time}

    In applying this general definition of speed↑to a wave, we have

                      speed of the wave=wavelength period

    Note: we generally use v for speed of a wave. Using the variable names, then that last formula is written

    v=λ ×T

    so  speed of the wave = 3× 6 =18\frac{m}{s}
