A rainbow is an optical and meteorological phenomenon that causes a spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the Earth’s atmosphere. They take the form of a multicoloured arc, with red on the outer part of the arch and violet on the inner section of the arch.
Rainbow is everywhere, you can see it in many different places. We have collected the following 30 Colourful and Peaceful Rainbow Photos. Hope the rainbow photos can make you happy and put a smile on your face.
