How are rainbows formed
How are rainbows formed?
Have you seen a rainbow? It is very colorful. You can not touch a rainbow, it is a light and you can only see it from a long distance. Read explanation to learn about how rainbows are formed.
A rainbow is made from light and a prism. If you shine your flashlight at a prism you get a rainbow. A rainbow is made when rain meets sunlight. The raindrops and sunlight act like prisms and flashlights. The sunlight goes inside the water droplet and it bends slightly and changes direction; this is called refraction. Note that no two people can see the exact same rainbow because each person is at a different angle and using different droplets of water. With that said, it is not possible to do it.
The colors on the rainbow are red, orange, yellow, green, blue, indigo and violet. Each color has a different wavelength and each one determines where the color should be. The color red has the longest wavelength because it is on the top of the rainbow, the colour violet has the shortest wavelength and that’s why it’s on the bottom.
Did you know that rainbows are actually full circles? Rainbows look like arches since we are seeing them from the ground. It seems like an arc but from the sight of a tall view such as a tall building, mountain or airplane but if you want to see a full circle rainbow, do not forget that you need to have sunlight and rain at the same time.
To make rainbows, you need sunlight and rain at the same time. Therefore, rainbows are rare and are colorful. They are very cool and stuff.
