BEUTY OF NATURE

A rainbow is an arc of color in the sky that can be seen when the sun shines through falling rain . The pattern of colors, called a spectrum , starts with red on the outside and changes through orange , yellow , green , blue , indigo , and violet on the inside. Sometimes a second, larger, dimmer rainbow is seen. A rainbow is a meteorological phenomenon that is caused by reflection , refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc . Rainbows caused by sunlight always appear in the section of sky directly opposite the Sun.
