If you change the wavelength of sound, the propagation speed in the tissue being imaged will change. True False

Adjusting which control on the ultrasound dashboard will result in a change to the wavelength of the ultrasound wave as it propagates through tissue?

Wavelength is directly proportional to frequency and indirectly proportional to propagation speed. True False

Brianna and Roger were conducting an experiment that involved sending sound waves through different materials. When the pair organized their data, they discovered that there was a pattern to the speeds the sound waves traveled. What can change the speed of sound through a material? Choose the two that apply. A. mass B. temperature C. length D. width E. density

In ultrasound imaging of the boundary between tissue A and tissue B, what would be the effect of increasing the difference in acoustic impedance between A and B?Group of answer choices(c) Reflected signal amplitude would decrease(d) Reflected signal amplitude would increase(a) Doppler signal would increase(b) Signal frequency would increase

If the speed of a wave is decreased, what is the effect on the wavelength? wavelength shortens wavelength expands wavelength deepens wavelength lengthens
