    (b) 0.491m

    Explanation:

    Given:

    Frequency, f = 698.46Hz

    Velocity, v = 343m/s

    Wavelength, λ = ?

    We know:

    velocity = wavelength X frequency

    Substituting the values in the formula we get:

    343 = wavelength X 698.46\\\\Wavelength = \frac{343}{698.46} \\\\Wavelength = 0.491m

    Therefore, the wavelength of the sound is 0.491m
