8. You and your goldfish Swimmy are looking at cach other through the sides of its fish tank filled with water (n = 1.33 = 4/3). If your and the fish's eyes are on the same normal line, where do you see each other (closer to or farther from the surface)? Draw at least two rays from each object to support your answer. How Swimmy sees you: How you see Swimmy: 9. If you are both a distance D from the side of the tank, what distance (from the side of the tank) do each of you perceive the other to be? (The glass is thin compared to D, so ignore its effect.) Swimmy says you are: You say Swimmy is:

Explanation / Answer

apparent depth in water will be x/refractive index and apparent depth for water in air will be (refractive index)*x

where x is the distance from medium.

Swimmy says you are = D+ (4D/3)= 7D/3

You says swimmy is = D+ (3D/4) = 7D/4
