When an ultrasound wave moves from muscle (1,580 m/s) to bone (4,080 m/s), the speed of the wave increases.
The frequency of a wave remains constant when transitioning between different media. However, the wavelength is determined by the speed of the wave divided by its frequency. Since the speed increases while the frequency remains constant, the wavelength must also increase.
So, the correct response is:
The wavelength of the wave increases.
