Answer: If a person's eardrum perceives a sound with a high pitch it can be predicted that, the wavelength must be short.
Explanation:
All the other options are untrue because of the following reasons:
- 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
- The short waves produce higher sound and long waves produce low sounds
