(Modeling) Fish’s View of the World The figure in the margin shows a fish’s view of the world above the surface of the water. (Source: Walker, J., “The Amateur Scientist,” Scientific American.) Suppose that a light ray comes from the horizon, enters the water, and strikes the fish’s eye.

Assume that this ray gives a value of 90° for angle θ₁ in the formula for Snell’s law. (In a practical situation, this angle would probably be a little less than 90°.) The speed of light in water is about 2.254 × 10⁸ m per sec. Find angle θ₂ to the nearest tenth.
