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. On the ground, we can not see perfectly, except if we are
in the high place like in the air plane or standing on top of moutain. When we are looking at rainbow’s
colors, we will see them that ordered of red is on the highest order, and purple is on the lowest order.
Red is more
dominant than another color caused by having biggest wave between others.
Therefore the red one is in the highest order
and purple one 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 colors on the light.
The light is rayyed to be some wave
lenght of light that it is seen by our eyes as red, bright red, yellow, green,
blue and purple. These colors are compnents 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).
So, we can see
the beautiful rainbow because there are some processes to be beautiful rainbow
that it appears in the sky.
