Ultrasound refers to sound waves that have frequencies that are higher than humans can hear. Information from ultrasound waves
that are reflected off objects can be used to make images.
Dr. Nolas is using an ultrasound machine to make images of objects that are in a liquid. The machine produces a wave that moves
through the liquid at a speed of 1,500 m/s and has a frequency of 25,000 Hz. What is the wavelength of the wave moving through
the liquid?
A. 0.080 m
B. 33.34 m
C. 0.060 m
D. 16.67 m
