(a) For the fish, the distance of bird from free surface is `(4h)/(3)` or 1.33 h, Distance of fish from the free surface = 0.5 h. So, the required distance is 1.83 h.

Again, effective distance of bird from the mirror is nh + h or 2.33 h. So, distance of bird's image from mirror is 2.33 h. Distance from fish is 2.33 h +0.5 h i.e. 2.83 h.
(b) For the bird, distance of fish from the free surface is `(h)/(2n) " or " (h)/( 2 xx 4/3) " or " (3h)/(8) ` or 0.375 h
Distance of fish from bird is 0.375 h + h i.e. 1.375 h. Again, distance of image of fish from mirror is ` h/2`
Effective distance (for the bird) of the image of fish is the mirror is
` 1/n | (3h)/(2) | + h "i.e." 3/4 xx (3h)/(2) + h " or " (9h)/(8) + h " or " (17h)/(8)` or 2.125 h .
