: Introduction to Rainbow
Rainbow, also known as Tiangong (Hakka), crosses the rainbow, blushes, etc. , 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 the differences. 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 drop, and then refract for the second time, and the water drop will still be emitted as monochromatic light.
