rasonic 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 ough the liver is 7.7% less than when it is traveling through the surrounding medium, determine the depth of the tumor. cm Surrounding material Liver Tumor 14.0 cm

A 45°-90°-45° prism is constructed from a synthetic resin. As shown in the figure, a light beam that enters the prism at the midpoint of the long side and parallel to the base exits the prism at an angle of 58° below the horizontal. What is the index of refraction of this prism? 1.749 Have you drawn a figure showing all angles and established any relationships between the angles? Have you written a Snell's law statement for the light as it enters and exits the prism? Depending on how you solve the problem, you may need the identities tan a = sin a / cos a and sin(a ± B) = sin a cos B ± cos a sin B.
