Rainbowsappear in the form of a multicolored bow. When caused by water and sun, rainbows appear on the side of the sky that is directly opposite the sun. They can be full circles at times, but to the average observer, only the arc will be visible. The colors in a rainbow are those found in the color spectrum of white light as it divides.

Rainbowis 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.

Whatare rainbows made of? Light waves. How do rainbows form? When sunlight hits the rain at the proper angle, the raindrops refract then reflect the light into the colors of a rainbow. Where do they form? In the sky, in puddles, in the spray of a hose or sprinkler, anywhere the following conditions are met - the observer has a light source
The properties and behaviour of light, and how it interacts with droplets of water, give rise to one of nature's most colourful meteorological events - the all in the geometry... Rainbows are formed when sunlight is scattered from raindrops into the eyes of an observer. Most raindrops are spherical rather than the often depicted 'teardrop' shape and it is this spherical shape that provides the conditions for a rainbow to be seen. The position of the sun and the raindrops in relation to the observer need to be just right for a rainbow to form The sun needs to be behind the viewer The sun needs to be low in the sky, at an angle of less than 42° above the horizon. The lower the sun in the sky the more of an arc of a rainbow the viewer will see Rain, fog or some other source of water droplets must be in front of the viewer The size of the raindrops does not directly affect the geometry of a rainbow, but mist or fog tends to disperse the effect more see fogbows. Rainbows only appear semi-circular over level ground at sunrise or sunset, when the sun is exactly on the horizon, the majority of the time a smaller segment of an arc is seen. The effect of light hitting a raindrop Because water is denser than air, light passing from air to a raindrop at an angle slows and changes direction, in a process called refraction. Sunlight is made up of light of many different wavelengths that slow by different amounts causing the white light to split, or disperse, with the shorter blue and violet wavelengths going through a slightly increased change of direction to the longer wavelengths of the red light. If the angles at which the light enters the droplet are correct, some of the light that enters the droplet will be internally reflected from the inside edge of the drop and will exit the drop, undergoing refraction again as it passes back from water to air. Seeing the rainbow An observer standing in the right place will see the dispersed sunlight reflected back towards them. Light scattered by many drops reaching the observers eye will appear as a colourful rainbow. Different colours exit the droplets at angles varying by around two degrees from red to violet. The red light seen by an observer comes from drops slightly higher in the atmosphere than the drops that scatter violet light towards the observer. The colours seen are not a pure spectrum, there is some mixing and blurring of the colours. The human eye can pick out many hues but it is still common to think of a rainbow as having seven colours, red, orange, yellow, green, blue, indigo and violet ROYGBIV.

Arainbow is formed because white light enters the water droplet, where it bends in several different directions. When these bent light waves reach the other side of the water droplet, they reflect back out of the droplet instead of completely traversing the water. Since the white light is separated inside of the water, the refracted light
A rainbow in the mountains of Thailand. It is commonly understood that a rainbow appears when sunny skies and raindrops combine, but what exactly is it about this combination that creates such vibrant colors in the sky? A rainbow forms as the result of the reflection and refraction of light. When sunlight enters a clear object, such as a prism or a raindrop, part of it is reflected while another part enters and is refracted. When sun hits a raindrop, its light is broken up into several difference colors. Rainbows are actually full circles - because we only see half of them, we process them as an arc. 3. Types of Rainbows There are many, many, many types of rainbows that exist. Here is a quick list of each type Rainbow Colorful arc that appears when it rains but the sun is shining opposite the observer. Secondary bow This bow usually appears outside the main bow, and is fainter after the light rays have escaped two whole reflections. In other words, the rainbow itself is being reflected in raindrops. The colors always appear in the opposite direction of a rainbow. Supernumeraries Closely spaced additional greenish purple arcs found inside even the violet color of the primary rainbow. These are formed by rays having different path lengths within each droplet. Red Bow Simply a rainbow seen at sunrise or sunset when light has to pass through the lower atmosphere, resulting in longer wavelengths of light. Rainbow Wheel A rainbow combined with crepuscular or in this case, anticrepuscular rays that converge on a point on the horizon. Dew Bow Fairly rare, these are created by dew drops on grass or in spider webs, and generally form a full halo. Dew bows are most commonly found in the autumn. Spray Bow A rainbow formed by the spray of a wave, waterfall, or geyser, and often a smaller arc than a normal bow. Glass Bead Bows These appear following the resurfacing of a road, and after that road dries. Because glass is more refractive, these bows are only half the size of rainbows. Twinned Bows A rare phenomenon where two rainbows seem to cross during heavy rainfall. There is no clear explanation for these yet, but the best theory seems to be that when heavy raindrops are flattened some by air resistance, they elongate, possibly producing both bows. Cloud Bows Also not very common, these bows are created without any actual rain, but instead small water droplets in the form of mist or damp air. . 2. Role In Religion And Mythology Since the dawn of civilization, the rainbow has been central to the folklore of many cultures. The Norse knew rainbows as Bifrost, a bridge that connected Earth to Asgard, the home of the Norse gods, and could only be accessed by gods and warriors killed in battle. In Hinduism, Indra was the god of thunder who used the rainbow to shoot arrows of lightning. Iris was the personified goddess of the rainbow in Ancient Greece. In Australian Aboriginal myth, the Rainbow Serpent is the creator of the world and everything on it. It was believed that during the dry season the Rainbow Serpent would retreat into a distant waterhole before finally returning for the rain. 1. How Common Are Rainbows? Seeing a rainbow is actually more rare than what is commonly led on. Even in a rainy place like England, there may be fewer than ten bright rainbows in a year. However, in locations that receive more rain, rainbows may be more common, since rainbows are merely caused by the reflection, refraction, and dispersion of light inside water droplets into the full spectrum of light in the sky, often set against the backdrop of darker storm clouds, which in turn highlights the rain droplets directing and scattering light and so shining bright inside the rainbow arc. Rainbows are always observed opposite the sun with no exception. Home Environment How Are Rainbows Formed?
Rainbowoften appears after the rain stops. Rainbow consists of a big bow spectrum and happens from water droplets which reflacted paralel because of the light of the sun. When the sun is shining and the light passing through water droplets, we can see a reflaction because of a wide variety of colors. The light passes and reflact like a light

How is Rainbow Formed?Rainbow is a natural phenomenon that is caused by the light refraction and reflections in the water drops, resulting in a spectrum of light appearing in the sky. A rainbow appears as a colorful arch. When they are caused by water and the sun, a rainbow shows up on the side of the sky that is directly facing the sun. They can become a complete loop at times, but for the average observers, only the arc will be seen. The colors in the rainbow will be the ones that can be found within the white light color spectrum as it divides. There are 7 main colors that you can see in the Rainbow which are red, orange, yellow, green, blue, indigo and violet. When the sunlight touches the water droplets, 7 colors emerge. When sunlight moving from air to water, the light colors are slowed down to various speeds - depends on their frequency. As purple light enters the raindrops, it bends at a sharp angle. On the right side of the water droplet, some light is passed back into the air, while the rest bounces back. Raindrops higher in the sky scatter the light so that only red light is visible to the observer's eyes. Droplets between red and violet reflect different colors, so the observer sees the full spectrum of colors. Sunlight striking rain in the atmosphere is refracted at the surface of the raindrop and enters the droplet. After refraction occurs, the light breaks into seven colors inside the raindrop; it is then reflected to the other side of the raindrop after traveling inside it. When the light in the raindrop refracts, a spectrum is formed to make the 7 colors of the rainbow appear. During reflection, the angle reflection is equal to the angle of incidence; this means that the reflected light travels along a set path and maintains the difference in the angle of refraction. A rainbow is a set of raindrops suspended in the atmosphere that divides sunlight into 7 colors, like a prism. Lihat Ilmu Sosbud Selengkapnya
So we make our own rain droplets from the water spray. In the morning or afternoon, spray water under the sun, then see the water droplets flying. Spray lots of water and you will see a small rainbow that you can touch easily. Second, use pieces of video discs then reflected the light of the sun, and navigate to the wall or ceiling of your house.
