An ultrasound transducer transmits a sound wave from air into a patient's soft tissue during a medical scan. The speed of sound in air is approximately 340 m s-1, whereas the speed of sound in soft tissue is approximately 1540 m s-1.
What happens to the speed, frequency, and wavelength of the ultrasound wave as it enters the soft tissue?
Speed decreases, frequency remains constant, wavelength decreases
Speed increases, frequency remains constant, wavelength decreases
Speed increases, frequency remains constant, wavelength increases
Speed increases, frequency increases, wavelength remains constant
