5. Extended information:

Rainbow, also known as Tiangong (Hakka dialect), rainbow over the sky, crimson and so on. , is an optical phenomenon in meteorology. When sunlight hits the water droplets in mid-air, the light is refracted and reflected, forming an arched colorful spectrum in the sky. From the outer ring to the inner ring, there are seven colors: red, orange, yellow, green, blue, indigo and purple. In fact, rainbows have countless colors. For example, there are many subtle differences between red and orange, but for simplicity, only seven colors are used as differences.

6. Sunlight consists of seven colors: red, orange, yellow, green, blue, indigo and purple. When it touches a water drop, it will be refracted for the first time. Because of the different wavelengths of these seven colors, their deflection angles will be different. At this time, sunlight will be decomposed into seven monochromatic lights; After the refracted monochromatic light reaches the back of the water drop, it will be reflected according to the reflection law; The reflected monochromatic light will return to this side of the incident water droplet, and then it will be refracted for the second time, and the water droplet will still be emitted as monochromatic light. In sunny weather, you can also spray water or mist in the air with your back to the sun to make artificial rainbows.
