    1. 10m/so

    2. 500Hz

    3. 0.81m

    4. 0.675m

    5. 25m/s

    Explanation:

    Speed = wavelength * frequency

    1. Speed = 50*0.2 = 10m/s

    2. Frequency = 100/0.2 = 500Hz

    3. Wavelength = 340/420 = 0.81m

    4. Wavelength = 270/400 = 0.675m

    5. Speed = 100*0.25 = 25m/s
