A rainbow is a stunning natural phenomenon that appears as a multicolored arc in the sky, typically seen after rainfall when the sun shines through the falling droplets. This beautiful sight is actually sunlight being refracted and reflected by the water droplets, splitting the white light into its constituent colors: red, orange, yellow, green, blue, indigo, and violet (VIBGYOR). Rainbows are often viewed as a symbol of hope and beauty, and their appearance can evoke feelings of wonder and joy. They are typically seen as a semicircle, but from an elevated viewpoint like an airplane, they can be seen as a full circle.
