    Answer:

    “332.8 m/s” is the right solution.

    Explanation:

    The given values are:

    Wavelength,

    \lambda=0.65 \ m

    Frequency,

    f = 512 \ Hz

    As we know,

    ⇒  Speed=Frequency\times Wavelength

    or,

    ⇒  V=f\times \lambda

    By putting the given values in the above relation, we get

    ⇒     =512\times 0.65

    ⇒      =332.8 \ m/s
