Question

can any one explain me "Bird and the Fish" problem... which is from 10th class physics (chapter 4)...​

Answer 1

Answer:

ANSWER

If the object is in rarer medium and the fish is looked from

the denser medium, we know Normal shift d=(n−1)h,

where h represents the real depth.

Again I the question it is given that h=y.

Therefore apparent depth or the height of the bird from

the water surface is y+(n−1)y=NY.

Hence the total distance is X+ny.

The option D is correct.
