Asked by grim

Humans can typically perceive frequencies that range from 20 Hz–20 kHz. Dogs can hear sounds up to 45 kHz. Dog whistles produce sound waves that range from 23–54 kHz; therefore, they cannot be heard by the human ear.

Which statement accurately describes the pitch and wavelength of the sound waves produced by a dog whistle?

high pitch with a long wavelength
high pitch with a short wavelength
low pitch with a short wavelength
low pitch with a long wavelength

High pitch with a short wavelength.

Explanation: Dog-whistle frequencies (23–54 kHz) are much higher than human hearing, so they have a high pitch. Wavelength λ = v/f (v ≈ 343 m/s in air), so higher frequency gives a shorter wavelength (≈0.015 m to 0.006 m, i.e., ~15 mm to ~6 mm).
