Could you please delete my post it was a true and honest mistake and I did not mean to post it. Thank you Have a good day

Explanation:

I don't think it's there anymore

Both frequency and wavelength will change. We perceive an increase of frequency as the increased pitch that you described. As the frequency (pitch) increases, the wavelength becomes shorter according to the universal wave equation ( v=fλ ).

Explanation:

If the frequency of a sound wave increases, the wavelength of the wave decreases. You hear the pitch of the sound from an ambulance siren get lower, then get higher.

( happy to help) :)
