A coin is fixed at the bottom of a vessel containing two immiscible transparent layers. The upper layer has thickness 8 cm and refractive index 1.333, while the lower layer has thickness 6 cm and refractive index 1.600. The coin is viewed normally from air. What is its apparent depth measured from the upper surface?
