Weba N w = 1.33 (refractive index of air/water interface from tables) Conversely w N a = 1 1.33 = 0.75 ( going from water to air) D r / D a = N (real depth / apparent depth = refractive index) So, D r / D a = N becomes. 3 m / D a = 0.75 D a = 3 / 0.75 = 4 m. The bird appears to be flying at 4 m above the water surface. WebJan 31, 2024 · In Fig. 1, \(h_a\) represents the apparent height of the observed starlight with respect to the Earth, and \(h_g\) represents the refracted height of the actual starlight, and \(h_a\) is slightly smaller than \(h_g\). \(R\) represents the stellar refraction angle, which is the angle between the refracted and unrefracted rays observed by the ... penal retaliatory crossword clue
