Velocity of sound is independent of frequency. Therefore it is same (v) for frequency n and un.

 

Effect of frequency on speed of sound -

With change in frequency of sound wave, wavelength also changes so that \nu \lambda = v =\: constant

- wherein

Thus, the speed of sound is independent of its frequency.
