If the frequency is tripled, what happens to the wavelength?

Explanation:
The wavelength and frequency are inversely related when the wave speed is constant. In ultrasound, speed in tissue stays roughly the same, so increasing frequency lowers the wavelength. Since v = fλ, tripling the frequency makes the new wavelength λ' = v/(3f) = (fλ)/(3f) = λ/3. So the wavelength decreases to about one third of its original value.
