What causes the temporary color separation seen when a star flashes red, blue, or green?
Answer
The atmosphere acts like a prism, separating wavelengths
When the atmosphere is agitated, it separates different wavelengths of light momentarily, similar to how a prism works, because shorter wavelengths bend more easily than longer ones.
