How do rainbows form?
Rainbow is formed due to the refraction of sunlight by water droplets in the atmosphere. When sunlight through water droplets, the light is bent in such a way as to make the colors that exist in the light separately. Each color bends at different angles, and the color red is the color most recently bent, while purple is the most first. This phenomenon which we see as a rainbow.
Why is the sky blue?
Earth's atmosphere contains a small gas molecules and particles (grain) dust. Sunlight entering the atmosphere is met with gas molecules and dust particles earlier. The color of light that has longer rays such as red and yellow, can pass through and penetrate the molecular gas and dust earlier. But the color blue has a shorter light waves reflected back into the upper atmosphere. That is why the sky looks blue. The same principle applies also to the water in the ocean or a lake that looks blue.
