The speed doesn't change. Wavelength is speed/frequency, so if the frequency doubles and the speed stays the same, the wavelength is cut in half.

The speed won't change. Only the temperature of the air can change the speed. (And the medium: sound travels faster in solids than in air.)
But because of the formula v=lf (where l is the wavelength and f is the frequency), a greater frequency will necessarly demands a lower wavelength in order for the speed to remain the same.
Although the pitch of the sound will change. A lower sound is due to a lower frequency.

Speed is independent of the frequncy of the sound wave it only changes with change in medium through which soun propagates; so speed remains unchanged.
As we know speed of sound is the product of wavelength and frequency of the sound and speed of the sound is not affected; as frequency is doubled wavelength of sound is exactly half of the original wavelength.

no change in speed, sound travles at a constant speed, the wave length will increase and become sharper because the waves are closer together
