from the bottom of pool, the apparent height of the bird will be same as the dist of the image of the bird...

apparent height of the bird is D+t(1-1Î¼)

where D is the dist b/w bird and floor and t is the thickness of the water column above the floor...

thus dist of the bird from its image is 2D+2t(1-1Î¼)

i think this should be the approach!

i'm sorry

it shud have been

2D-2t(1-1Î¼)

giving some 11/2 as answer!
