To find the distance between the bird and the fish as seen by the bird, we can follow these steps: ### Step 1: Identify the heights and depths - The height of the bird (HB) from the surface of the water is 60 meters. - The depth of the fish (HF) from the surface of the water is 40 meters. ### Step 2: Understand the concept of apparent depth - When viewed from above the water, the fish will appear to be at a different depth due to refraction. The apparent depth (HF') can be calculated using the formula: ...
