A rainbow is a beautiful arch of colors that appears in the sky after it rains. Its colors go from red, orange, yellow, green, blue, indigo, and violet. People have been amazed by rainbows for thousands of years. Legend says that a Greek goddess named Iris used rainbows as bridges to travel between heaven and earth.
Rainbows happen when sunlight is divided into its different colors by raindrops in the air. The raindrops act like tiny prisms that bend the light, making it split into the familiar colors of the rainbow. It’s like magic!
Rainbows are usually seen after a rainstorm, when the sun comes out and shines on the raindrops. But you can also see a rainbow if there are waterfalls, fountains, or even just a spray of water in the air. In fact, any time there are water droplets in the air and sunlight, there is a chance to see a rainbow.
Each color in a rainbow has a different wavelength, which is why we see them as separate colors. The red light has the longest wavelength, and the violet light has the shortest wavelength.
Sadly, you can never reach the end of a rainbow because it’s an optical illusion. A rainbow appears to be in one place, but if you move closer, it seems to move away. It’s like a sneaky game of hide and seek!
So, the next time you see a beautiful rainbow in the sky, remember that it’s caused by sunlight and raindrops working together to create a colorful spectacle for us to enjoy. It’s nature’s way of saying, “Look how amazing I can be!”
