Answer:
Hello your question is incomplete attached below is the missing part of the question
answer : ( d / D ) = [tex]n_{a}[/tex]
[tex]n_{w}[/tex]
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 ) = [tex]n_{a}[/tex]
[tex]n_{w}[/tex]
where [tex]n_{a}[/tex] = index of refraction ( air )
[tex]n_{w}[/tex] = index of refraction ( water )
