‘How do Rainbows Form?’ is one of the important topics on which students can be asked to write a paragraph in exams in school. Rainbows appear when sunlight bends, reflects, and splits inside water droplets, creating a beautiful arc of colors in the sky. Please check the various versions (in 100 words, 150 words, 200 words, and 300 words) provided below for the paragraph.
Paragraph on ‘How do Rainbows Form?’ in 100 words
Rainbows form when sunlight hits water droplets in the air. When the sunlight enters the droplet, it bends or refracts. The light then splits into different colors. Each color bends by a different amount. The light then reflects off the inside of the droplet and exits back out. This is why we see a rainbow in the sky. The colors we see in a rainbow are red, orange, yellow, green, blue, indigo, and violet. The sun has to be shining and there need to be rain or water drops in the air for a rainbow to appear.
Paragraph on ‘How do Rainbows Form?’ in 150 words
Rainbows happen when sunlight shines through water droplets in the air. When the sunlight enters a droplet, it bends or refracts. This is because light moves slower in the water than in the air. The light then splits into different colors. Each color bends by a different amount. Red bends the least, and violet bends the most. After splitting, the light reflects off the inside of the droplet and bends again as it exits. This is what makes a rainbow. The colors you see in a rainbow are red, orange, yellow, green, blue, indigo, and violet. To see a rainbow, you need sunlight and rain or water droplets in the air. The sun should be low in the sky, and you should look toward the opposite side of where the sun is shining.
Paragraph on ‘How do Rainbows Form?’ in 200 words
Rainbows form when sunlight shines on water droplets in the sky. The sunlight enters each droplet, bends, and slows down because light moves slower in water than in air. As the light bends, it splits into different colors. These colors are red, orange, yellow, green, blue, indigo, and violet. Each color bends by a different amount. Red light bends the least, and violet light bends the most. After splitting, the light hits the inside of the water droplet and reflects, or bounces back. The light then exits the droplet at a different angle, creating the colors we see. To see a rainbow, you need both sunlight and water droplets in the air, like after it rains. The sun has to be shining, and you should be standing with your back to the sun. The rainbow will appear in the opposite part of the sky. The more droplets there are, the brighter the rainbow will be. Each rainbow is made of millions of tiny droplets that bend and reflect the sunlight in different ways.
Paragraph on ‘How do Rainbows Form?’ in 300 words
Rainbows form when sunlight interacts with water droplets in the atmosphere. The process begins when sunlight enters a water droplet. As the light enters the droplet, it bends or refracts, because light travels at different speeds in different substances. In this case, light moves more slowly in water than in air. When the light bends, it splits into many colors. Each color bends by a different amount. Red light bends the least, while violet light bends the most. After splitting, the light reflects off the inside surface of the water droplet. This reflection causes the light to travel back through the droplet and exit in a different direction. The result is a colorful arc in the sky, which we see as a rainbow. The colors in a rainbow are red, orange, yellow, green, blue, indigo, and violet. These colors always appear in the same order. To see a rainbow, you need both sunlight and water droplets in the air. This usually happens after it rains, when the sun shines through the remaining raindrops. The sun needs to be low in the sky, and you should be standing with your back to it. The rainbow will appear in the opposite direction, and the more water droplets in the air, the more vivid and bright the rainbow will be. A rainbow is made up of millions of tiny water droplets, each bending and reflecting light in its own way. Every time you see a rainbow, it’s a result of these small droplets working together to create a beautiful display of colors in the sky.

Colorful Rainbow Activity
A colorful rainbow activity helps children learn about light refraction and dispersion by creating rainbows using prisms, water droplets, or DIY experiments with sunlight.
Formation of rainbow
A rainbow forms when sunlight passes through raindrops, bending (refraction), splitting into colors (dispersion), and reflecting inside the droplet before emerging as a beautiful arc.
What does a rainbow mean?
A rainbow symbolizes hope, diversity, and new beginnings. Many cultures see it as a sign of peace, good fortune, or a bridge between realms.
Why does the sky appear blue?
The sky appears blue because Earth’s atmosphere scatters sunlight, and shorter blue wavelengths scatter more than other colors, making the sky look blue to our eyes.
What Causes Eclipses?
Eclipses occur when one celestial body blocks another. A solar eclipse happens when the Moon blocks the Sun, while a lunar eclipse occurs when Earth shadows the Moon.
What is Light and How Does it Travel?
Light is electromagnetic radiation traveling in waves or particles called photons. It moves in straight lines but can bend, reflect, or refract through different mediums.
