Answer» Solution :We know, if object is in rarer MEDIUM and OBSERVER in the denser medium then refractive INDEX of denser medium, `mu = ("apparent height of the object")/("real height of the object")` `"Here", " " mu_(w) = ("apparent height of the object (x)")/("real height of BIRD")` `therefore "" x = mu_(w) xx d` `therefore "" mu_(w) gt 1` `therefore "" x gt d` Therefore to the fish, the bird appears to be slightly higher than its actual POSITION. |
