Rainbows Rainbows are created when sunlight of different wavelengths (colors) is refracted and reflected in raindrops. The angle of elevation θ of a rainbow is always the same. It can be shown that θ = 4β − 2α. Where
and α = 59.4° and k = 1.33 is the index of refraction of water. Use the given information to find the angle of elevation θ of a rainbow. [Hint: Find sin β, then use the
