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 11.5% 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 11.5 cm from its entry point. Calculate the depth of the tumor (in cm) below the surface of the liver.

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 11.5% 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 11.5 cm from its entry point. Calculate the depth of the tumor (in cm) below the surface of the liver.
