1. The English word for a rainbow is "rainbow."
2. The moon casts a rainbow through the spray of a waterfall.
3. The second rainbow will be larger than the first and located directly above it.
4. The dispute between New Zealand and France over the "Rainbow Warrior" incident has been officially resolved.
5. Expanded information: A rainbow, also known as a celestial bow (in Hakka), a skybow, or jiang, among other names, is an optical phenomenon in meteorology. When sunlight passes through半空中的water droplets, the light is refracted and reflected, forming an arch-shaped spectrum of seven colors in the sky. These colors, from the outside to the inside, are red, orange, yellow, green, blue, indigo, and purple. In fact, a rainbow contains an infinite number of colors. For example, there are many subtle differences between red and orange, but only seven colors are commonly used for distinction.
6. sunlight is composed of seven colors: red, orange, yellow, green, blue, indigo, and purple. When it照射到water droplets, it undergoes the first refraction. Due to the different wavelengths of these seven colors, they are refracted at different angles. At this point, sunlight is separated into seven monochromatic colors. After refraction, these monochromatic colors reach the back of the water droplet and are reflected according to the law of reflection. The reflected monochromatic colors return to the front side of the droplet and undergo a second refraction before exiting the droplet. On a clear day, facing away from the sun and sprinkling water or creating a mist in the air can also produce an artificial rainbow.
