Hello your question is incomplete attached below is the missing part of the question
answer : ( d / D ) = 

Step-by-step explanation:
Given data:
Apparent distance = distance calculated using angle ∅a
also applying the approximation ; sin(x) ≈ x and asin(x) ≈ x
Find the ratio of apparent distance to real distance (d / D )
Using the given data in the question the ratio of apparent distance to real distance ( d / D ) = 

where
= index of refraction ( air )
= index of refraction ( water )
