Two identical beakers are filled to the same height h=20cm. Beaker A contains only water (n=1.33). Beaker B contains two immiscible liquids of equal height 10cm each: Liquid X (n=1.5) at the bottom and Liquid Y (n=1.2) at the top. Determine the ratio of the apparent depth of the bottom of Beaker A to the apparent depth of the bottom of Beaker B.
