5) Sydney is performing an ultrasound scan. The scanner sends a signal of frequency 4.25MHZ that enters the liver from blood. Liver has an attenuation coefficient of 0.17dB/cm-MHz. Determine a) the speed of the sound wave in liver, b) the angle of refraction into liver, given the signal is incident at an angle of 37.2° as it enters the liver from blood, c) the reflection coefficient, R, of the signal between blood and liver.
