Answer:
The fish appears nearer to the cat than it really is
Step-by-step explanation:
The situation above is related to the refraction of light. The cat will think that the fish is closer to him, however, it is actually at a different depth in its actual position. This is because of the refraction of light as it travels in two different mediums: water and air. The eyes and brains are not capable of tracing the light rays' refraction, thus, the cat's image of the fish is on a shallower depth. In reality, the light rays reflecting from the fish are actually being refracted on the water's surface.
