What is a nijiro? A nijiro, or "rainbow" in Japanese, is a meteorological phenomenon that is caused by the refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured arc, with red on the outer edge and violet on the inner edge.
Rainbows are caused by sunlight interacting with raindrops. When sunlight enters a raindrop, it is refracted, or bent. The different colors of light are refracted at different angles, which causes them to separate. The light then reflects off the back of the raindrop and is refracted again as it leaves the raindrop. This causes the light to be dispersed, or spread out, into a rainbow.
Rainbows are often seen after rainstorms, when there are still water droplets in the air. They can also be seen near waterfalls or other bodies of water that create mist. Rainbows are a beautiful sight and are often considered to be a symbol of hope and new beginnings.
In Japanese culture, the rainbow is known as a niji. The niji is often seen as a symbol of good luck and happiness. It is also associated with the Shinto goddess Amaterasu, who is the goddess of the sun.

Shape
Rainbows are always shaped like an arc because of the way that light is refracted and dispersed by water droplets. When sunlight enters a water droplet, it is refracted, or bent. The different colors of light are refracted at different angles, which causes them to separate. The light then reflects off the back of the raindrop and is refracted again as it leaves the raindrop. This causes the light to be dispersed, or spread out, into a rainbow.
The shape of a rainbow is determined by the angle of the sun and the position of the observer. The sun must be behind the observer and the raindrops must be in front of the observer in order to see a rainbow. The higher the sun is in the sky, the lower the rainbow will be in the sky. The closer the observer is to the raindrops, the smaller the rainbow will be. Rainbows are often seen after rainstorms, when there are still water droplets in the air. They can also be seen near waterfalls or other bodies of water that create mist.
The arc shape of a rainbow is an important part of what makes it such a beautiful and iconic natural phenomenon. The arc shape is what gives rainbows their characteristic shape and it is what makes them so easy to recognize.
Size
The size of a rainbow is determined by the angle of the sun and the position of the observer. The sun must be behind the observer and the raindrops must be in front of the observer in order to see a rainbow. The higher the sun is in the sky, the lower the rainbow will be in the sky. The closer the observer is to the raindrops, the smaller the rainbow will be.
The typical size of a rainbow is about 42 degrees in diameter. This means that the rainbow will appear to be about 42 degrees wide when viewed from the ground. However, rainbows can vary in size, depending on the factors mentioned above.
The size of a rainbow is an important part of what makes it such a beautiful and iconic natural phenomenon. A large rainbow can be a breathtaking sight, and even a small rainbow can be a thing of beauty. Rainbows are a reminder of the beauty that can be found in the natural world, and they are a symbol of hope and new beginnings.
Location
Understanding the location of rainbows in relation to sunlight is crucial for capturing their essence and beauty. Rainbows appear opposite the sun, forming a captivating celestial display. This phenomenon is attributed to the interplay of light, water droplets, and the observer's vantage point.
- Light's Path: Sunlight, composed of various wavelengths, undergoes refraction and dispersion as it enters a raindrop. These wavelengths are bent and separated, creating the rainbow's spectrum of colors.
- Water Droplets as Prisms: Raindrops act as tiny prisms, refracting and reflecting sunlight. The angle at which sunlight strikes the raindrop determines the direction of the refracted light, leading to the rainbow's arc shape.
- Observer's Position: The observer's position relative to the sun and raindrops plays a vital role. To witness a rainbow, the sun must be behind the observer, while raindrops are situated in front. This alignment allows the refracted and dispersed light to reach the observer's eyes.
Comprehending the location of rainbows enhances our appreciation for their beauty and scientific underpinnings. It enables us to seek out optimal viewing conditions, maximizing the vibrancy and clarity of this natural spectacle.
