The wavelength will remain unchanged.
Explanation:
The velocity of a wave in terms of its wavelength
and frequency
is
(1)
so if we double both the velocity and the frequency, the equation above becomes
(2)
Solving for the wavelength from Eqn(2), we get
We would have gotten the same result had we used Eqn(1) instead.
