1. The problem statement, all variables and given/known data A 2 meter deep swimming pool is filled with water. A mirror is placed at the bottom and a small fish swims 5 cm (0.05m) below the surface. If you look at the swimming pool from above, how deep does the fish appear to be (a), and how deep does it's image appear to be (b)? a1 = 0.05 m a2 = 2.00 m n_air = 1 n_water = 1.33 2. Relevant equations n1/a1 + n2/a2 = (n2 - n1)/r 3. The attempt at a solution Not so sure with (a), but without using the formula or anything on (b), my intuition tells me that the mirror-image should be 15+15+5 centimetres below the surface. Would really appreciate some help with (a) and some input. Thanks in advance!
