Answer» The correct answers are 8 m and 7 m.Explanation:The expression for the refractive index in terms of apparent DEPTH in air is as follows;Put and REAL depth in air= 3 m.The FISH would see the bird at 4+4 = 8 m.The bird would see the fish at 3 m + 4 m= 7 m.Therefore, the fish would appear to the bird at depth of 8 m. The bird would appear to fish at the HEIGHT of 7 m. |
