If the whole set up is immersed in water without disturbing the object and the screen positions, what will one observe on the screen ?
Image disappears
Magnified image
Erect real image
No change
Explanation
From $${1 \over F} = \left( {{\mu _{rel}} - 1} \right)\left( {{1 \over {{R_1}}} - {1 \over {{R_2}}}} \right)$$
Focal length of lens will change hence image disappears from the screen.
