Suppose the figure below represents a ray of light going from air through crown glass into water, such as going into a fish tank. Calculate the amount the ray is displaced by the glass (Ax in mm),given that the incident angle is 43.5° and the glass is 1.05 cm thick.01n,02n202-Ax-n3mm 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 thetumor, and refract back into the surrounding medium. If the speed of the wave as it travels through the liver is 2.8% less than when it is traveling through the surrounding medium, determine thedepth of the tumor.cmLiverTumorSurroundingmaterial55°14.0 cm
