🌈 A rainbow is like magic in the sky! It happens when the sun shines on tiny drops of water in the air, like after it rains. The sunlight bends and splits into beautiful colors, just like when you shine light through a prism!
Next time you see a rainbow, try to spot all seven colors: red, orange, yellow, green, blue, indigo, and violet!
🌈 A rainbow is created when sunlight passes through raindrops in the air. The light bends (refracts) as it enters the raindrop, reflects off the inside, and bends again as it exits. This splits the white sunlight into its seven colors: red, orange, yellow, green, blue, indigo, and violet!
Rainbows always appear opposite the sun, so you’ll see them when the sun is behind you and rain is in front of you.
🌈 A rainbow is an optical phenomenon caused by the refraction, reflection, and dispersion of sunlight in water droplets. When sunlight enters a raindrop, it slows down and bends (refraction). The light then reflects off the inner surface of the drop and refracts again as it exits, splitting into its component wavelengths (colors).
The angle between the incoming sunlight and the reflected light is about 42 degrees, which is why rainbows form a circular arc. You might even see a double rainbow if light reflects twice inside the droplets!
Rainbows are full circles, but we usually only see the top half because the ground blocks the lower part.
