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. The rainbow takes the form of a multicoloured circular arc.
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.
Jul 2, 2024 · rainbow, series of concentric coloured arcs that may be seen when light from a distant source—most commonly the Sun—falls upon a collection of water drops—as in rain, spray, or fog. The rainbow is observed in the direction opposite to the Sun.
All about rainbows. What causes a rainbow, why is it curved? What are the rainbow colors, how does a double rainbow work, and what's at rainbow's end?
Rainbows are formed by the dispersion of light & reflection (not total internal reflection) from drops of water. The rainbow color sequence can be analyzed by drawing a ray diagram of the refraction of sunlight inside water drops. Created by Mahesh Shenoy. Questions.
How Rainbows Are Made. A rainbow can form when both sunshine and water droplets are in the sky. Sunlight is white light, which is a mixture of all visible colors. As sunlight passes through the water droplets, it is bent and split into seven colors: red, orange, yellow, green, blue, indigo, and violet. You might be able to see a faint second ...
When Isaac Newton originally observed a rainbow of light split by a prism and made his labeling of the colors as red, orange, yellow, green, blue, indigo, violet, the thing he called blue was indeed what we would now call blue-green, or teal, or cyan. Reminiscent of the color of the blue sky.
The Colors of a Rainbow. Since sunlight is made of different wavelengths of light, we see the white light broken into an array of colors—the rainbow. The colors of the rainbow in order, are red, orange, yellow, green, blue, indigo, and violet.

The rainbow is one of the most beautiful, naturally occurring phenomenons in nature. Scientifically speaking, rainbows appear in the sky when sunlight enters raindrops, causing dispersion and refraction of the light. But rainbows symbolize so much more than just a scientific anomaly.
