Two tuning forks with frequencies of 256 Hz and 512 Hz are struck. Which of the sounds will move faster through the air?

1 Answer

The same.

Explanation:

The velocity of sound in any gaseous medium is given by:

#c =sqrt{\frac{K_s}{\rho}}#

Where,

#K_s# is a coefficient of stiffness, the isentropic bulk modulus (or the modulus of bulk elasticity for gases)

#rho# is the density.

It does not depend on the frequency of itself. Though the bulk modulus may vary with frequency, but I am not sure those minute details are required here.
