Why is the sky blue?
You look up on a sunny day, and there it is: blue everywhere. Not green, not purple, not the wild orange of a sunset — just blue, stretching from horizon to horizon like someone painted the whole sky with one giant brush. So what's going on up there?
Here's the thing: sunlight looks white to us, but it's actually a mix of every color of the rainbow packed together. Red, orange, yellow, green, blue, violet — they're all traveling from the sun to Earth in one beam. Think of sunlight as a band where every musician plays a different note at once, and together it sounds like one chord.
