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?

Options

A. 1.033 cm
B. 3.581 cm
C. 1.3533 cm
D. 1.90 cm

Answer

C

Explanation

`"Real depth"=5cm+1cm=6cm`
`"Apparent depth"=(d_(1))/(mu_(1))+(d_(2))/(mu_(2))+….`
`=(5)/(1.33)+(1)/(1.5)`
`=3.8+0.7=4.5cm`
`therefore" Shift "=6cm-4.5cm~=1.5cm`
