How Rainbow is Formed ?

Rainbow is one of optic phenomena that happens in the atmosphere of the earth naturally. We can see it at mountin range, or when it is cloudy, or when it is raining and rising of sun. We have to be the other side for looking. We just can see it a half of circle form, but acctually the rainbow is a circle form. We can see it perfectly, if it is seen by standing in the high place. It is real that rainbow is a circle form not like parabola form.

Red colour is more dominant than another colour caused by having biggest wave between others. Therefore the red colour is in the highest order and purple colour is in lowest order. How rainbow is formed? Try to watch it when light of sun concerns a 90-degree angle mirror or a glass prism side, or surface of soap foam. We can see colours on the light. The light is rayyed to be some wave lenght of light that it is seen by our eyes as red, orange, yellow, green, blue, indigo and purple. These colours are components of light that they are called visible light. The other component is invisible light such as infrared (red is in the right side), and ultraviolet (bright red is in the left side).
