A shallow glass dish is $4.00 c m$ wide at the bottom, as shown in figure. When an observer's eye is positioned as shown, the observer sees the edge of the bottom of the empty dish. When this dish is filled with water, the observer sees the centre of the bottom of the dish. Find the height of the dish. $(μ_{w} = 4 / 3)$ .
