A) \[x+y\left( 1-\frac{1}{n} \right)\]
B) \[x+ny\]
C) \[x+y\left( 1+\frac{1}{n} \right)\]
D) \[y+x\left( 1-\frac{1}{n} \right)\]
Correct Answer: B
Solution :
When object is in rarer medium and observer is in denser medium Normal shift, \[d=(n-1)h\] where h = real depth Here, h = y Now, apparent depth or the apparent height of the bird from the surface of the water \[=y+(n-1)y=ny.\] The total distance of the bird as estimated by fish is x + ny.You need to login to perform this action.
