An ultrasound transducer emits a longitudinal wave that travels through air and then enters a patient's muscle tissue. The speed of sound in air is 340 m s-1 and the speed of sound in muscle tissue is 1580 m s-1.
What happens to the speed, frequency, and wavelength of this ultrasound wave as it enters the muscle tissue?
Speed increases, frequency stays the same, wavelength increases
Speed increases, frequency decreases, wavelength stays the same
Speed decreases, frequency stays the same, wavelength decreases
Speed decreases, frequency increases, wavelength decreases
