If a person's eardrum perceives a sound with a high pitch what can be predicted about the wavelength of the sound wave?

the wavelength is double the pitch.
the wavelength must be short.
the wavelength must be long.
the pitch of sound is not related to the wavelength.

If a person's eardrum perceives a sound with a high pitch it can be predicted that, the wavelength must be short.

Explanation:

A person’s hearing frequency range is between 20Hz to 18000 Hz.

The higher the frequency the shorter the wavelength and the higher the pitch

The lower the frequency the lower the pitch and longer the wavelength

Frequency and wavelength are inversely proportional to each other. And it can be said that short waves produce higher sound and long waves produce low sounds.
