Sunny days are always fun, but rainy days can be exciting too! I love playing in the rain and jumping in puddles. Sometimes, if you’re lucky, it can be sunny and rainy at the same time, which is the perfect moment to see a rainbow.
Have you ever wondered what a rainbow really is? You can’t touch it, and there’s no pot of gold at the end, even though that would be amazing! So, let’s find out how rainbows form.
The light from the sun is made up of all the colors we can see, mixed together. We call this white light. A rainbow happens when this light meets a drop of water. Here’s how it works:
This bending and reflecting of light inside the water droplet is what creates a rainbow.
In a rainbow, you will see red on the outside and violet on the inside. This happens because each color is a different wavelength of light, and they bend by different amounts. You can see a similar effect using a prism. When you shine light through a prism, it splits the light into all the colors of a rainbow, just like magic!
Rainbows can appear anytime light interacts with water droplets, not just after rain. For example, you might see a rainbow in the mist of a waterfall or even in the spray from a garden hose on a sunny day.
Rainbows are a beautiful reminder of the wonders of nature and the science of light. Next time you see one, you’ll know exactly how it forms!
Make Your Own Rainbow: Try creating a rainbow at home! On a sunny day, take a garden hose and spray water into the air with the sun behind you. Observe the colors that appear in the mist. Can you see a rainbow? Try changing the angle of the hose and see how it affects the rainbow. Discuss with a friend or family member why you think the rainbow appears and disappears.
Prism Experiment: If you have a prism, shine a flashlight through it in a dark room. Watch as the light splits into different colors on the wall or a piece of paper. Draw what you see and label the colors. Talk about how this is similar to how a rainbow forms in the sky.
Color Hunt: Go on a color hunt around your home or classroom. Find objects that match the colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet. Arrange them in order and create your own rainbow display. Think about how these colors appear in nature and where you might see them in a rainbow.

Sunny days are always fun, but I like rainy days too! I don’t mind getting a bit wet when I play in the rain or jump in puddles. With a bit of luck, it can also be sunny and rainy at the same time—the perfect time to see a rainbow.
You can’t touch a rainbow, and as much as you wish for it to be true, there’s no pot of gold at the end. So what exactly is a rainbow, and how do they form?
The light from the sun is actually a mixture of all the colors in the visible light spectrum; we call this white light. A rainbow is caused by light being refracted when entering a droplet of water, then reflected inside the back of the droplet, and refracted again when leaving it.
In a primary rainbow, the arc shows red on the outer part and violet on the inner side. We can model and observe a rainbow using a prism. When the prism is placed between the source of light and a solid surface, the light is broken up into all the colors of a rainbow. This is because each color is a different wavelength of light, and the prism bends the different wavelengths by different amounts.
In nature, a rainbow can form whenever light interacts with water droplets. What other ways can rainbows form?
