Explanation text provides information about explanations and the process of rainbow formation: - Explanations tell the processes relating to natural, social, scientific, and cultural phenomena in order to describe how or why things occur. - Rainbows are an optic phenomenon that occurs naturally in the atmosphere when sunlight interacts with water droplets at a 90 degree angle, refracting and dispersing the light into wavelengths that appear as colors. - The order of colors in a rainbow is red at the top descending to violet at the bottom due to the different wavelengths of light, with red having the longest wavelength.

6. 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 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. 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 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).
So, we can see the beautiful rainbow because there are some
processes to be beautiful rainbow that it appears in the sky.
