conclusion on some natural phenomena
A process or event that occur in nature constantly is known as natural phenomena. These phenomenon are not artificial and are not controlled by humans. For example, the formation of rainbow. Rainbow forms when sunlight hits the water droplets suspended in the atmosphere and undergoes total internal reflection. When the sunlight comes out of the drop it disperses, where the drop acts like a small prism. This dispersion or breaking up of light into several colors is what forms the Rainbow.
