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.
When light exits the droplet, it makes a rainbow. Learn how raindrops act like tiny prisms and refract white light into a spectrum of colors. Discover the physics of light, the angles of refraction, and the symbolism of rainbows.
Visibility A colorful rainbow and ring-billed gull Rainbows can be observed whenever there are water drops in the air and sunlight shining from behind the observer at a low altitude angle. Because of this, rainbows are usually seen in the western sky during the morning and in the eastern sky during the early evening. Why These Colors Appear The appearance of these specific colors in a rainbow, and their ordered arrangement, is a result of sunlight interacting with countless water droplets through processes called refraction and dispersion.
Few natural spectacles capture our imagination quite like rainbows. These ethereal arcs of color stretching across the sky after a rainstorm have fascinated humans for millennia, inspiring myths, art, and science alike. Yet a rainbow is far more than a simple splash of color.
A rainbow is caused by the refraction, dispersion, and reflection of sunlight as it passes through raindrops. As light passes through raindrops, it bends at different rates causing it to spread out into the colors of the visible spectrum. The light is then reflected within the raindrop and emerges to create the appearance of a rainbow.
A rainbow appears when sunlight shines through water droplets in the air, often during or after it rains. Each tiny droplet acts like a prism, bending and reflecting the sunlight, which causes the light to split into its different colors. Explore how rainbows are formed, what they mean in weather, and the science behind their colors.
