GENERAL STATEMENT Rainbow is one of optic phenomena that happens in the atmosphere of the earth naturally. We can see it at mountain 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 actually 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.

SEQUENCED EXPLANATION Rainbow formed by the refraction of sunlight by water pressure in the atmosphere. Rainbows happen when sunlight and rain combine in a very specific way. When sunlight through water droplets, the light is bent in such a way that makes the colors that exist in a separate light. The beams of sunlight separate into the colors we see in the rainbow as they enter a raindrop. Sunlight is actually made up of different colors that we don't usually see. The sun itself has multiple colors called polychromatic.

When a beam of sunlight comes down to Earth, the light is white. But, if the light beam happens to hit raindrops on the way down at a certain angle, the different colors that make up the beam separate so that we can see them in the form of a rainbow.

Some of this coloured light is reflected back off the internal surface of the raindrop, similar to a mirror. When we see this reflected light, the reason that we see each colour separately is that each colour of light bends back out of the raindrop at a slightly different angle, so we see all red light at an angle of 42 degrees between us and the sun, and all violet light at an angle of 40 degrees between us and the sun and the other colours at angles between 40 and 42 degrees. You can see a diagram of how this works in the next slide!

Light enters a water droplet, bending as it slows down a bit going from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths—or colors. When it exits the droplet, it makes a rainbow.

CLOSING PARAGRAPH The angle for each color of a rainbow is different, because the colors slow down at different speeds when they enter the raindrop. The light exits the raindrop in one color, depending on the angle it came in, so we see only one color coming from each raindrop. Light at different angles coming through many raindrops form the rainbow that we see, in stripes of red, orange, yellow, green, blue, indigo and violet.
