How Do Rainbows Occur?
Don’t we all love watching rainbows after a heavy shower? Have you ever wondered how rainbows are formed? A rainbow is a phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. For example, if you take a prism and white paper and pass a ray of light through the prism, you’ll notice that a band of seven colours/a rainbow formed on the surface of the white paper. So, when a rainbow is formed, the sky acts like a white paper or canvas, and the water droplets present in the atmosphere act as the prism through which the sunlight passes and forms a rainbow arch.
