    A)  Wavelength    

    B)  Frequency

    C)  Velocity                              

    D)  Amplitude

    Correct Answer: B

    Solution :

Sound waves of different frequencies travel with the same speed in air although their wavelength in air are different. If the speed of sound were dependent on frequency, then we could not have enjoyed the orchestra.
