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 on 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?
