When sunlight passes through raindrops in the air, it gets refracted or bent, causing the different colors in the light spectrum to separate. This separation creates a circular rainbow formation in the sky, with red on the outer edge and violet on the inner edge. As the angle between the light, raindrops, and observer changes, the rainbow can appear to move or disappear altogether.
A rainbow shows up overhead when daylight is refracted (bowed) and inside reflected inside raindrops. This is the way it works out:
1. **Refraction:** When daylight passes from air into a raindrop, it dials back and curves as it enters the denser mechanism of water. This bowing of light is called refraction.
2. **Internal Reflection:** Inside the raindrop, the light is inside gleamed off the internal surface of the drop. This interior reflection makes the light discrete into its different varieties, making a range.
3. **Dispersion:** The various shades of light, each with a somewhat unique frequency, are fanned out and frame a circle of varieties. Red light is twisted the least, and violet light is bowed the most, with different in the middle between.
4. **Emergence:** After the inside reflection and scattering, the light leaves the raindrop, and the outcome is a roundabout circular segment of varieties overhead.
A rainbow commonly shows up as a crescent circular segment, yet when you see a round trip, it's frequently from a raised perspective, for example, a mountain ridge.
Rainbows vanish as the raindrops that were making them move or change position. Assuming that the downpour stops, or the point of daylight changes fundamentally, the rainbow will vanish. Raindrops are continually falling, so rainbows are transitory and persistently shaping and dispersing as the circumstances change.

Rainbows form when sunlight is refracted upon entering raindrops, causing the light to split into its component colors. This refraction occurs due to the varying speeds at which different colors of light travel, leading to their dispersion within the water droplets. The dispersed light is then reflected inside the droplets before being refracted once more upon exiting, creating the distinctive arc of colors in the sky. Rainbows disappear as the angle between the observer, sunlight, and water droplets changes. If this angle shifts, the dispersed light may no longer be directed toward the observer, resulting in the fading of the rainbow. Additionally, as the rain shower diminishes, the reduced number of water droplets in the atmosphere can cause the rainbow to vanish.
Rainbows show up and vanish because of the refraction, scattering, and impression of daylight by raindrops in the environment. This is the way a rainbow frames and disappears: 1. **Sunlight Entering Raindrops**: A rainbow starts when daylight, which is comprised of different tones (range of noticeable light), enters raindrops in the climate. Each variety in daylight has an alternate frequency. 2. **Refraction**: When daylight enters a raindrop, it goes through refraction, which is the twisting of light as it passes from one medium (air) into another (water). This bowing happens on the grounds that the speed of light changes when it moves from air into denser water. 3. **Dispersion**: As the light keeps on going inside the raindrop, it likewise goes through scattering. Scattering is the detachment of light into its singular tones (range). The various shades of light are refracted by differing sums, making them spread out. 4. **Reflection**: After scattering, the light glistens off within surface of the raindrop. This reflection happens on the grounds that within surface goes about as a mirror. 5. **Refracted Again**: The light then leaves the raindrop out of sight. As it leaves, the various shades of light are refracted once more, twisting as they move from the denser water once more into the less thick air. 6. **Formation of a Circle**: The shades of light are presently fanned out in a roundabout example, shaping a round trip of varieties. Be that as it may, the ground deters the base portion of this circle, so we generally see a semi-roundabout rainbow. 7. **Viewing Angle**: To see a rainbow, you should be remaining with your back to the sun, looking toward the area where raindrops are available. The light from the raindrops enters your eyes, and you see the delightful bend of varieties. 8. **Size of Water Drops**: The size of the raindrops likewise influences the size and splendor of the rainbow. Bigger raindrops make bigger, more clear rainbows. 9. **Disappearing Rainbow**: A rainbow will seem when the ok circumstances are met, yet it can vanish when these circumstances change. Assuming that the downpour stops or on the other hand if the point between the approaching daylight, raindrops, and your survey position changes altogether, the rainbow will evaporate. Rainbows are optical peculiarities that require explicit circumstances to happen, including the presence of raindrops and daylight. While they appear to show up and vanish, they are dependably there; it's simply a question of your review point and the air conditions.
The appearance and disappearance of a rainbow in the sky are dependent on specific atmospheric conditions, sunlight, and the observer's position. Here's an explanation of how rainbows appear and disappear:
**1. Raindrops and Sunlight Interaction:**
- Rainbows require raindrops and sunlight. When rain is falling and there is sunlight (or any other visible light source), the conditions are right for a rainbow to potentially form.
**2. Refraction and Dispersion:**
- As sunlight enters a raindrop, it slows down and bends due to refraction. At the same time, dispersion occurs, separating the white light into its individual colors (spectrum).
**3. Internal Reflection and Refraction:**
- Inside the raindrop, the separated colors undergo internal reflection off the inner surface of the droplet. This reflection is what allows the colors to curve and form a circle or arc.
**4. Exiting the Raindrop:**
- After reflection, the colors exit the raindrop while continuing to refract. The exact angle at which each color exits the raindrop depends on its wavelength.
**5. Observing the Rainbow:**
- To see a rainbow, you need to be positioned with your back to the sun (facing away from it) and looking toward the area where sunlight is interacting with falling raindrops. The rainbow will appear in the sky in the direction opposite to the sun.
**6. Rainbow Appearance:**
- A primary rainbow, with its sequence of colors from red on the inside to violet on the outside, forms the familiar half-circle shape in the sky.
**7. Multiple Rainbows:**
- Under certain conditions, you can observe a secondary rainbow outside the primary one. The secondary rainbow has the colors arranged in the reverse order, with red on the outside.
**8. Disappearance of Rainbows:**
- Rainbows can disappear for several reasons:
- The rain showers stop, and the raindrops needed to create the rainbow are no longer present.
- The sun's angle changes so that it is no longer at the correct angle for refraction and reflection inside raindrops.
- Cloud cover or other obstructions block the sunlight needed to create a rainbow.
Rainbows are transient phenomena and can be relatively short-lived. They may also change in intensity and visibility as atmospheric conditions change. To witness a rainbow, you need the right combination of sunlight, rain, and your viewing position. Once these conditions are met, a rainbow can appear, and its visibility and duration will vary based on the factors mentioned above.

A rainbow appears when daylight is refracted (bowed) and inside reflected inside water drops in the environment, making a range of varieties. The cycle includes scattering, where the daylight is isolated into its different varieties because of various frequencies. This outcomes in the natural curve of varieties.
Rainbows can disappear when the circumstances that make them change. This can happen when the downpour showers creating the water drops stop, the point of the daylight changes, or the eyewitness' position changes. Rainbows are optical peculiarities, so they are dependent upon explicit circumstances to be noticeable.
