    Answer: 60m/s

    Explanation:

    The wavespeed is the distance covered by the wave in one second. It is measured in metre per second, and represented by the symbol V

    Wavespeed (V) = Frequency F x wavelength λ

    i. e V = F λ

    In the first case:

    Wavespeed = 30 m/s

    Frequency of sound = 6Hz

    Wavelength = 5m

    In the second case:

    Wavespeed = ?

    Frequency of sound = (2x 6Hz = 12Hz)

    Wavelength = 5m (remains constant)

    Apply V = F λ

    Wavespeed = 12 Hz x 5m

    Wavespeed = 60m/s

    Therefore, when frequency is doubled, the speed is also doubled. Thus, the new speed of the wave is 60m/s
