Ultrasonic diagnostics may be used to locate a tumor in an organ such as the liver. The figure shows a beam of ultrasonic waves that enter the surrounding medium, refract into the liver, reflect off the tumor, and refract back into the surrounding medium. If the speed of the wave as it travels through the liver is 5.7% less than when it is traveling through the surrounding medium, determine the depth of the tumor. cm
