Afish appears to be 2.00 m below the surface of a pond (nwater = 1.33) when viewed almost directly above by a fisherman. what is the actual depth of the fish?

Explanation:

The given data is as follows.

     Apparent depth = 2.00 m,  refractive index = 1.33

It is known that formula to calculate real depth is as follows.

   The refractive index =

or,       real depth = refractive index × apparent depth

Now, putting the given values into the above formula as follows.

               real depth = 1.33 × 2

                                 = 2.66 m

Thus, we can conclude that the actual (real) depth of the fish is 2.66 m.
