If an ultrasound wave moves from one tissue to another tissue in the body, which of the following transitions or result in the largest change, and the wavelength of an ultrasound, wave muscle to kidney fat to liver liver to muscle blood to Fat
The largest change in wavelength of an ultrasound wave will occur when it transitions from one medium to another with a different acoustic impedance (Z). Acoustic impedance is determined by the product of the density and the speed of sound in a medium.
From the provided options, the largest change in wavelength will occur when the ultrasound wave transitions from muscle to kidney. This is because muscle and kidney have different acoustic properties, resulting in a larger change in acoustic impedance compared to the other options.
Wavelength is inversely proportional to the frequency of the ultrasound wave, meaning that a larger change in wavelength will correspond to a larger change in frequency.
