The bow in a rainbow is caused by the refraction, dispersion, and reflection of light in water droplets in the atmosphere. This process separates the sunlight into its various colors, creating the arch of colors that we see in the sky.

What makes a double rainbow appear in the sky?

A double rainbow appears in the sky when sunlight is reflected twice inside raindrops, creating a secondary rainbow above the primary one.


Why do you see a rainbow after a rainstorm?

After a rainstorm, sunlight is refracted and reflected by raindrops in the air, creating a spectrum of colors called a rainbow. Each raindrop acts like a prism, dispersing the sunlight into its different wavelengths, which form the colors of the rainbow.


What is the difference between primary rain bow and secondary rain bow?

Rainbows are formed when light is reflected and refracted around the inside of water droplets. When the droplets get to a certain size, the light is reflected an additional time, creating a secondary rainbow.The reason you see both a primary and a secondary rainbow (or even higher orders of rainbow) is that the water droplets which are reflecting the light have different sizes. Some of them are large enough to fit the extra reflection inside them, whereas some are not.


Why is it common to see rainbows near waterfalls even though it isn't raining?

Rainbows occur when sunlight is refracted and reflected by water droplets in the air. Waterfalls create mist and spray that can act as water droplets, providing the conditions necessary for a rainbow to form even when it's not raining. The sunlight interacts with the mist in the air to produce the colorful spectrum we see as a rainbow.


What happens when you shine a rainbow into a prism?

Depending on the positioning of the prism, it will merge the rainbow back together or spread the eight rays even further. Using this tactic, it is possible to concentrate light even further inwards, depending on how you orient the prism. If an edge is facing the light, it will spread. If a face is facing the light, it will converge.
