Sound waves undergo reflection and refraction, much as electromagnetic waves do. Here is one practical application of reflection and refraction in the field of health care: determining the location of a liver tumor Suppose that a narrow beam of ultrasonic waves travels through surrounding tissue and enters the liver with an incidence angle of 48.0. These inaudible sound waves travel 10.5% more slowly through the liver than through the medium that lies above. Suppose that the beam reflects off the tumor and emerges from the liver at a distance 13.0 cm from its entry point. Calculate the depth of the tumor (in cm) below the surface of the liver 13.0 cm 48.0 cm Liver Tumor
