The glowing of a neon light is caused by electrons emitting energy as they move from higher to lower energy levels.
Explanation:
Because each color is refracted conversely, each includes at a discrete angle, resulting in a fanning out and detachment of white light into the colors of the spectrum. Water droplets in the air can act in a practice similar to that of a prism, quitting the colors of sunlight to generate a spectrum accepted as a rainbow.
