Introduction: Have you ever wondered how a rainbow is formed? Well, today we are going to learn all about rainbows! Rainbows are beautiful arcs of colors that appear in the sky after it rains. They are a magical sight to behold and have fascinated people for centuries. So, let’s dive into the world of rainbows and discover how they are created!

Paragraph: Rainbows are formed when sunlight passes through raindrops in the air. When it rains, the sunlight breaks into different colors called the spectrum. These colors include red, orange, yellow, green, blue, indigo, and violet. Each color has a different wavelength, which is the distance between the peaks of the waves. As the sunlight enters the raindrop, it bends or refracts. This bending of light causes the different colors to spread out and form a circle of colors in the sky. The raindrop acts like a tiny prism, which is a special kind of glass that can separate light into its different colors. When the light exits the raindrop, it reflects off the inside surface and then refracts again. This causes the colors to spread out even more, creating the beautiful arc shape we see as a rainbow.

Conclusion: In conclusion, rainbows are formed when sunlight passes through raindrops and gets refracted and reflected. The different colors of the spectrum spread out and form a circle of colors in the sky. So, the next time you see a rainbow after a rain shower, remember that it is nature’s way of showing us the beauty of light and water working together. Rainbows are truly a magical phenomenon that never fails to bring joy and wonder to our lives!
