What causes a rainbow in water?
The fundamental process at work in a rainbow is refraction-- the "bending" of light. Light bends -- or more accurately, changes directions -- when it travels from one medium to another. This happens because light travels at different speeds in different mediums.

- What Causes a Rainbow
A rainbow is an optical phenomenon caused by refraction, internal reflection and dispersion of light in water droplets resulting in a continuous spectrum of light appearing in the sky. [1] . The rainbow takes the form of a multicoloured circular arc. [2] .
Oct 19, 2023 · Vocabulary. A rainbow is a multicolored arc made by light striking water droplets. The most familiar type rainbow is produced when sunlight strikes raindrops in front of a viewer at a precise angle (42 degrees). Rainbows can also be viewed around fog, sea spray, or waterfalls.

Sep 11, 2024 · A rainbow is caused by sunlight and atmospheric conditions. Light enters a water droplet, slowing down and bending as it goes from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths--or colors.
