When the sunlight strikes raindrops in the air, they act like a prism and form a rainbow. The rainbow is a division of white light into many beautiful colors. These take the form of an arc round the long length and both ends appear to be beyond the horizon. According to legend, there is a pot of gold at the end. People look, but nobody is. When a man looks for something beyond his reach, his friends say he is looking for the pot of gold at the end of the rainbow.
