Rainbows are usually known for their brilliant colors—but under certain conditions, they can appear almost completely white.
In this episode, we explore the fascinating science behind fogbows, sometimes called white rainbows. These rare atmospheric phenomena form when sunlight interacts with extremely tiny water droplets in fog, creating a pale, ghostly arc instead of the vivid spectrum we normally expect.
Why do the colors disappear? How are fogbows different from ordinary rainbows? And what other strange optical illusions can the atmosphere create?
We explore the science of light, water droplets, and atmospheric conditions to uncover why one of nature’s most colorful spectacles can sometimes turn almost completely white.
Because even when the colors disappear… the physics behind the rainbow is still extraordinary. 🌈
