    Question:-

    The speed of a wave is 40 m/s. If the wavelength is 80 centimeters, what is the frequency of the wave ?

    Answer:-

    Given:-

    Velocity (V) = 40 m/s

    Wavelength  (\lambda) = 80 cm = 0.8 m

    To Find:-

    The frequency (F) of the wave.

    Solution:-

    We know,

        \bf V \: = \: F \: × \: \lambda

    40 = F × 0.8

    F =  \frac{40}{0.8}

    F = 50

    The frequency of the wave is 50 Hz. [Answer]
