Answer

Answer:

First drop - down: wavelength Second drop - down: pitch

Brief Explanations:

The speed of sound in air is constant for all sound waves. The relationship between speed ($v$), frequency ($f$), and wavelength ($\lambda$) is $v = f\lambda$. Since $v$ is constant, higher frequency means shorter wavelength. Also, pitch is directly related to frequency, so high - frequency sound waves have a higher pitch.
