A printed page is pressed by a glass of water. The refractive index of the glass and water is 1.5\: \: and\: \: 1.33, respectively. If the thickness of the bottom of glass is 1 cm and depth of water is 5 cm, how much the page will appear to be shifted if viewed from the top? 

Option: 1

1.033\: cm


Option: 2

3.581\: cm


Option: 3

1.3533\: cm


Option: 4

1.90\: cm

\begin{aligned} &\text { The apparent depth is, } h^{\prime}=\frac{h_{1}}{\mu_{1}}+\frac{h_{2}}{\mu_{2}}=\frac{1}{1.5}+\frac{5}{1.33}=4.43 \mathrm{cm}\\ &\text { normal shift } \Delta h=h-h^{\prime}=6-4.43=1.57 \mathrm{cm}\\ &\therefore \end{aligned}

So option C most appropriate correct option.
