    Answer:

    2.5 m/s

    Explanation:

    The speed of a wave can be found using the following formula.

    v= λ * f

    where  λ is the wavelength in meters (m) and f is the frequency of the wave in Hertz (Hz).

    We know the wavelength is 0.5 m and the frequency of the wave is 5 Hz.

    Therefore,

    λ= 0.5 m

    f = 5 Hz

    v= 0.5 * 5

    Multiply 0.5 by 5, or divide 5 by 2.

    0.5 * 5= 2.5     or      5/2=2.5

    v= 2.5

    Add appropriate units. The units for wave speed are m/s (meters per second).

    v= 2.5 m/s

    The speed of the wave is 2.5 meters per second.
